Supported Gem /152 ⍟

Active Skill Gem	Description
Fireball	Unleashes a ball of fire towards a target which explodes, damaging nearby foes.
Ice Nova	A chilling circle of ice expands from the caster. If the caster targets near their Frostbolt projectiles, it will expand from a number of those projectiles instead. If this skill would repeat when cast this way, it will instead expand again from the same projectiles after a short delay.
Immortal Call	Take less Physical and Elemental Damage for a short time. Consumes up to 5 Endurance Charges to lengthen the buff and further lessen Physical Damage taken. Shares a cooldown with other Guard skills.
Cold Snap	Creates a sudden burst of cold in a targeted area, damaging enemies. This also creates an expanding area which is filled with chilled ground, and deals cold damage over time to enemies. Enemies that die while in the area have a chance to grant Frenzy Charges. The cooldown can be bypassed by expending a Frenzy Charge.
Raise Zombie	Raises a zombie minion from a corpse, which will follow you and attack enemies with a melee attack and an area of effect slam which cannot be evaded.
Detonate Dead	Targets a corpse, and deals spell damage to enemies around the corpse, as well as causing the corpse to explode, dealing fire damage. The explosion is not affected by modifiers to spell damage and cannot be reflected.

Unearth	Fires a projectile that will pierce through enemies to impact the ground at the targeted location, creating a Bone Archer corpse where it lands.
Creeping Frost	Fire an icy projectile that bursts on impact or when reaching the targeted area, dealing area damage and creating a chilling area that deals cold damage over time. This area will creep across the ground towards nearby enemies until its duration expires.
Blood Rage	Adds a buff that deals Physical Damage over time, while increasing Attack Speed and Life Leech. Killing an enemy while this buff is active refreshes the buff duration, and can grant a Frenzy Charge.

Frost Wall	Creates a wall of ice which holds back enemies. Targets under the wall are damaged and pushed back.
Freezing Pulse	An icy projectile which has a chance to freeze enemies it passes through. The projectile fades quickly, reducing damage and freezing chance until it dissipates.
Shock Nova	Casts a ring of Lightning around you, followed by a larger Lightning nova. Each effect hits enemies caught in their area with Lightning Damage.

Performing any skill replaces this buff with one that boosts melee physical damage of skills you use yourself (it will not apply to your melee skills used by totems).

Punishment	Curses all targets in an area, causing them to be debilitated when they hit enemies and increasing damage they take while on low life. Some overkill damage from a killing blow on a cursed enemy will be reflected to surrounding targets.
Enfeeble	Curses all targets in an area, reducing their accuracy and making them deal less damage.
Assassin's Mark	Curses a single enemy, making them more vulnerable to Critical Strikes. Killing the cursed enemy will grant life and mana, and a power charge. You can only have one Mark at a time.

When the buff expires or is depleted, the skill deals reflected damage to enemies around you based on the total damage that was taken from the buff. Shares a cooldown with other Guard skills.
Arc	An arc of lightning stretches from the caster to a targeted enemy and chains on to other nearby enemies. Each time the main beam chains it will also chain to a second enemy, but that secondary arc cannot chain further.

Vaal Spark	Continuously launches unpredictable sparks in all directions that move randomly until they hit an enemy or expire.

Vaal Cold Snap	Creates a sudden burst of cold around you, damaging enemies. This also creates a chilling area around you which expands and deals cold damage over time to surrounding enemies in addition to chilling them.

Bladefall	Ethereal weapons rain from the sky, dealing damage to enemies in a sequence of volleys, each wider but less damaging than the last. Enemies can be hit multiple times where these overlap.

Vaal Blade Vortex	Creates an independently-moving vortex of ethereal blades which lasts for a duration. The vortex moves toward nearby enemies, repeatedly damaging enemies that it passes through.
Frost Bomb	Creates a crystal that pulses with cold for a duration. Each pulse applies a debuff to nearby enemies for a secondary duration which reduces life and energy shield regeneration rate, and also inflicts Cold Exposure. When the crystal's duration ends, it explodes, dealing heavy cold damage to enemies around it.
Orb of Storms	Creates a stationary electrical orb that strikes enemies in its area of effect with beams of lightning that can then split to hit more enemies. Modifiers to cast speed will increase how frequently it does this. Casting this skill again will replace the previous orb.
Summon Stone Golem	Summons a Stone Golem that grants you life regeneration. In addition to its melee attack, the Stone Golem uses a rolling charge and a powerful slam that can taunt enemies.
Contagion	Unleashes a vile contagion on enemies, dealing chaos damage over time. If an enemy dies while affected by Contagion, it spreads to other enemies.

Frostbolt	Fires a slow-moving projectile that pierces through enemies, dealing cold damage.

Scorching Ray	Unleash a beam of fire that burns enemies it touches. Remaining in the beam intensifies the burning, adding a portion of the beam's damage in stages. Inflicts Fire Exposure at maximum stages. Enemies who leave the beam continue to burn for a duration. Increasing cast speed also increases the rate at which the beam can turn.
Dark Pact	This spell removes some life from one of your Skeleton minions near you or the targeted location to deal chaos damage in an area around it. This effect will chain to your other nearby skeletons. If you have no skeletons near you or the targeted location, it will sacrifice your own life to deal damage instead.
Storm Burst	Unleash orbs of energy while you channel that repeatedly jump towards the targeted location until their duration expires, dealing damage in small area after each jump. When you stop channelling, all remaining orbs explode, dealing higher damage in a larger area.
Cremation	A targeted corpse explodes, dealing area damage and turning into a volcanic geyser, which will repeatedly unleash projectiles sequentially over the surrounding area for a duration. The explosion of the corpse is not affected by modifiers to spell damage, and cannot be reflected.
Bodyswap	Violently destroys your body and recreates it at the location of a targeted enemy or corpse, dealing spell damage in an area at both locations.

If targeting a corpse, the corpse will also explode, dealing damage around it that is not affected by modifiers to spell damage, and cannot be reflected. This spell cannot be repeated.
Vulnerability	Curse all targets in an area, causing them to take increased physical damage. Attacks against the cursed enemies have a chance to inflict bleeding, and ailments inflicted on them will deal damage faster.
Vaal Blight	Apply a powerful debuff to enemies around you which deals chaos damage over time. Then applies two additional layers in a larger area, growing greatly in size each time. Enemies are also substantially hindered for a shorter secondary duration, slowing their movement.
Summon Holy Relic	Summon a Holy Relic that stays near you. When you hit an enemy with an attack, the Holy Relic triggers a nova spell, with a very short cooldown, that deals physical damage to enemies and grants life regeneration to allies. This life regeneration is higher when applied to minions.
Winter Orb	Channel to conjure an orb above you, which pelts nearby enemies with projectiles that impact the ground and explode. Channelling for longer builds up stages on the skill. When you stop channelling, the stages decay over a duration.
Storm Brand	Creates a magical brand which can attach to a nearby enemy. It periodically activates while attached, firing beams which deal damage to nearby enemies and those around them. The brand will detach if the enemy dies.
Armageddon Brand	Creates a magical brand which can attach to a nearby enemy. It periodically activates while attached, causing a fiery meteor to fall from the sky. The brand will detach if the enemy dies.
Brand Recall	Recall your brands to you, detaching them from enemies and increasing attachment range until they next attach to an enemy. Spends a portion of each recalled brand's cost to cause it to activate.
Purifying Flame	A wave of divine fire deals damage in a line, then creates Consecrated Ground and deals damage in an area around the targeted location. A larger shockwave then expands outwards, damaging enemies standing on Consecrated Ground that were not already hit.
Soulrend	Fires a projectile that turns towards enemies in front of it, damaging and piercing through those it hits, and leeching some of that damage as energy shield. As the projectile travels, it repeatedly applies a short but powerful chaos damage over time debuff to each enemy in an area around it.
Bane	Applies a debuff to enemies in an area, which deals chaos damage over Time. Linked hex curses are also applied to those enemies. The debuff deals more damage and lasts longer for each hex applied this way. This skill cannot be used by Totems, Traps, or Mines.
Stormbind	Channel to spread runes on the ground in a growing pattern. The runes fade away after a duration, or will be immediately removed and deal damage in a circular area when detonated by Rune Blast. Enemies standing on the runes are Hindered, reducing their movement speed.
Divine Ire	Channelling draws in energy around you to repeatedly build up stages, damaging a number of nearby enemies when you do so. Release to unleash a powerful burst of energy in a beam in front of you.
Wave of Conviction	An expanding wave of energy surges forward, damaging enemies in a cone-shaped area over a duration. Each enemy hit is inflicted with Exposure matching the element of which they took the highest damage. Only one Wave of Conviction can be active at a time
Steelskin	Applies a buff which can take some of the damage from hits for you before being depleted. Shares a cooldown with other Guard skills.
Dash	Performs a series of quick teleports towards a targeted location. If using the "Attack in Place" option, the direction is reversed. Shares a cooldown with other Blink skills.

Summon Carrion Golem	Summons a Carrion Golem that grants added physical damage for your non-golem minions. The Carrion Golem attacks with a series of slashes that increase in speed and damage, as well as a cascade of bone spikes, and deals more damage for each of your non-golem minions near it.
Withering Step	Removes any existing Elusive buff before applying both Elusive and a buff that grants Phasing. While you have this buff, monsters that enter an area around you will be Withered. Using a skill or losing the Elusive buff ends this skill's effects. Shares a cooldown with other Blink skills.
Plague Bearer	Gain an Incubating buff, adding to its Plague Value as you inflict poisons. Use the skill again to begin Infecting, dealing chaos damage over time to nearby enemies until the Plague Value is depleted. Your damage modifiers don't apply to this skill's damage. Using the skill again alternates between Incubating and Infecting.
Arcane Cloak	Spends a portion of your mana to grant a buff that takes some of the damage from hits for you until depleted. The buff grants added lightning damage based on the amount of mana spent by this skill. Shares a cooldown with other Guard skills.
Blade Blast	Deals spell damage in a targeted area. When this spell deals damage, if your Lingering Blades or Blade Vortex blades are nearby, it will detonate them, dealing damage again in an area around them. Up to 50 Blades can be detonated this way.
Arcanist Brand	Creates a magical brand which can attach to a nearby enemy. It periodically activates while attached, triggering linked spells. The brand will detach if the enemy dies.
Penance Brand	Creates a magical brand which can attach to a nearby enemy. It periodically activates while attached, adding energy to the branded enemy. Each activation, energy spreads from each energised enemy to an enemy in range which is not energised by the brand. If the branded enemy has 20 energy, each activation will instead deal a pulse of area damage. Energy explodes when the energised enemy dies or the brand is removed, dealing damage in an area.
Wintertide Brand	Creates a magical brand which can attach to a nearby enemy, dealing cold damage over time and chilling them. It periodically activates while attached, gaining stages that raise the damage. When removed, a short-duration debuff dealing the same damage over time and chill is applied to each nearby enemy. The brand keeps its charges while detached.
Blazing Salvo	Fires projectiles which fly in an arc, exploding on impact with either enemies or the ground near where you target. Targeting farther away causes the projectiles to spread out and land over a wider area.
Void Sphere	Creates a Void Sphere which Hinders enemies in an area around it, with the debuff being stronger on enemies closer to the sphere. It also regularly releases pulses of area damage. The Void Sphere will consume the corpses of any enemies which die in its area. Can only have one Void Sphere at a time.
Crackling Lance	Release a beam which deals lightning damage to enemies in a long area in front of you, and has several smaller beams branch off from it at an angle, hitting more enemies to the sides.
Frost Shield	Place a Frost Shield that drains your energy shield for one second or until you run out, gaining stages while this drain occurs. The Frost Shield takes some damage from hits in place of you and allies while in its area. Enemies in the area are Chilled. You can only have one Frost Shield active at once.
Sigil of Power	Places a Sigil on the ground, which grants a buff to you and allies in the area around it for a duration. The Sigil gains stages as you spend mana in its area, making the buff more powerful. You can only have one Sigil of Power at a time.
Flame Wall	Create a wall of fire for a duration, which deals burning damage to everything in its area. Each enemy that enters the wall also receives a secondary burning debuff which persists for a short duration after leaving the wall. Any projectiles fired through the wall by you and allies deal added fire damage and apply the wall's secondary debuff on hit.
Hexblast	Deals chaos damage to a single enemy, dealing more damage if they are Hexed, then removes the Hex with the highest Doom. If a Hex was removed this way, also deals area damage to other enemies around the target, boosting damage and removing Hexes from those enemies in the same way.
Hydrosphere	Create a sphere of water, or move an existing sphere and reset its duration. The sphere continually applies a drenched debuff with a short duration to enemies in its area or those it moves through. You can hit the sphere with other skills to inflict Cold and Lightning Ailments (other than Chill). The sphere pulses when created, at regular intervals while afflicted by an Ailment, and after moving, damaging all drenched enemies in a large area.
Exsanguinate	Releases several tendrils of blood from your character, targeting enemies in a narrow angle in front of you. The beams deal physical damage and inflict a physical damage over time debuff to enemies, which can stack up to 3 times. Effects which allow skills to chain can apply to these tendrils.
Corrupting Fever	Draws out your own blood to power a buff for a duration, letting this skill inflict the Corrupting Blood debuff on enemies you hit, dealing physical damage over time for a short secondary duration. The buff's duration will be refreshed if you spend enough life before it expires.
Reap	A bloody scythe swipes across a selected area, applying a physical damage over time debuff in addition to hitting enemies with physical damage. If enemies survive, you gain a blood charge which raises the damage and cost of the skill. Players can have 5 maximum blood charges.
Voltaxic Burst	Each cast of this spell waits for a short duration, releasing a burst of lightning and chaos spell damage in an area around you when that duration ends. Enemies killed by this damage, or shortly after, will explode. The explosions of the corpses are not affected by modifiers to spell damage, and cannot be reflected.
Absolution	Damages enemies in an area, applying a debuff for a short duration. If a non-unique enemy dies while affected by the debuff, the enemy's corpse will be consumed to summon a Sentinel of Absolution for a longer secondary duration, or to refresh the duration and life of an existing one instead if you have the maximum number of them.
Ambush	Teleports you to a nearby enemy, applying a buff to you for a short duration and blinding the enemy for a secondary duration. Performing a melee attack with a One-Handed Weapon removes the buff to exert that attack.
Forbidden Rite	Lobs an exploding projectile near the targeted location, and extra projectiles toward enemies around you. The projectiles deal chaos damage based on your life and energy shield. Casting this spell damages you.
Manabond	Deals lightning damage based upon your missing mana in a circular area around the targeted location, as well as in four rectangular extensions whose lengths depend upon your remaining mana.
Summon Reaper	Summons a powerful Reaper which uses a variety of slashing area attacks. The Reaper's presence weakens your other minions, and it will consume them to temporarily empower and heal itself. Using this skill while the Reaper is already summoned causes it to dash to the targeted location and perform a powerful attack.
Eye of Winter	Fires a single eye projectile which constantly releases shard projectiles in a spiral. The shards will damage enemies they impact, dealing cold damage. The eye cannot damage enemies. When the eye dissipates or collides with terrain, it releases a faster spiral of extra shards.
Tornado	Create a Tornado that hinders and repeatedly damages enemies around it. It will move forward for a duration, during which your projectiles can collide with it to deal damage as though it was an enemy. Then it will chase down enemies for a secondary duration, and reflect a portion of the damage it took from your projectiles to them in addition to its own damage.
Energy Blade	Grants a buff which significantly lowers your maximum Energy Shield to transform your equipped weapons into Swords formed from that energy. Casting the spell again removes the buff. Requires a Non-Bow weapon. This skill cannot be triggered.
Soul Link	Targets an allied player to apply a buff which links you to them for a duration. While linked, your Energy Shield will intercept some of the damage they would take. If the target dies while linked, you will also die. This skill cannot be triggered, or used by Totems, Traps, or Mines.
Flame Link	Targets an allied player to apply a buff which links you to them for a duration. While linked, they deal additional fire damage based on your life. If the target dies while linked, you will also die. This skill cannot be triggered, or used by Totems, Traps, or Mines.
Vampiric Link	Targets an allied player to apply a buff which links you to them for a duration. While linked, they get recovery from your life leech instead of you. If the target dies while linked, you will also die. This skill cannot be triggered, or used by Totems, Traps, or Mines.
Protective Link	Targets an allied player to apply a buff which links you to them for a duration. While linked, they copy your block chance and recover life when they block. If the target dies while linked, you will also die. This skill cannot be triggered, or used by Totems, Traps, or Mines.
Intuitive Link	Targets an allied player to apply a buff which links you to them for a duration. While linked, their hits can trigger your supported spells. If the target dies while linked, you will also die. This skill cannot be triggered, or used by Totems, Traps, or Mines.
Destructive Link	Targets an allied player to apply a buff which links you to them for a duration. While linked, they use your main hand critical strike chance. If the target dies while linked, you will also die. This skill cannot be triggered, or used by Totems, Traps, or Mines.
Lightning Conduit	Lightning strikes all Shocked enemies around a targeted location, then removes Shock from those enemies. Shocks cannot expire on enemies in range while casting this spell. Cannot be supported by Spell Cascade or Unleash.
Galvanic Field	Applies a buff boosting chance to shock. When you shock an enemy while you have this buff, creates a spherical field of energy attached to the shocked enemy for a duration, which will damage it and other nearby enemies with beams of lightning. The strength of the field depends on the magnitude of shock affecting the enemy when it is created.
Alchemist's Mark	Curses a single enemy, granting flask charges when you hit them and creating Burning Ground under them if your hit Ignites them, and Caustic Ground if it Poisons them. Damage modifiers do not apply to these ground effects. You can only have one Mark at a time.

Arcane Surge Support

ArcaneSurge Arcane Surge Support is a Support gem that grants the Arcane Surge buff when the total mana spent reaches a threshold.

Skill functions and interactions

Interaction with Totem, Trap, & Mine Skills: Spending mana by placing a Totem, Trap, or Mine will not go towards gaining the Arcane Surge buff. Totems, traps, and mines that cast the skill also do not go towards gaining the buff.
Duration: Increases and reductions to duration will apply to the duration of the buff. Additionally, it adds a duration component to the linked skill, which makes it supportable by support gems like Less Duration Support and Swift Affliction Support (which apply their damage bonus), even if the active skill gem does not otherwise have a duration of its own.
Vaal Skills: This will not add the duration tag to a Vaal skill for the purposes of reducing soul gain prevention via skill effect duration reduction.
Eldritch Battery and Blood Magic: The buff will only activate if mana is spent. Spending Energy Shield or Life for the supported skill will not activate the buff.
Elreon's Signature Mod: If used with a skill such that the total mana cost of the skill is zero or less, it will not count as spending mana towards the Arcane Surge, and will never activate it.
When equipped on multiple skills, the Arcane Surge Grants buffs are applied globally and depend on the support gem level of the trigger skill. The More Spell Damage while you have Arcane Surge modifier is applied locally, and thus each support gem can have a different level (and therefore, different damage multiplier).
