Blight
A channelled, area of effect chaos spell that applies a debuff to enemies. Debuffed enemies take chaos damage over time as well as having reduced movement speed.
Increases the duration of Blight's slow effect and chaos damage over time debuff on enemies.
Steelskin
Strengthen your defense, greatly reducing damage taken from hits for a short duration. Steelskin is a Guard utility skill that blocks an amount of damage. Once depleted, the damage will go through to you. Guard skills do not benefit much from support gems, and Steelskin can be used well without supports.
Allow Steelskin's bonus to last longer, to defend against more hits from enemies. A simple but valuable way to improve defense.

Battlemage's Cry
Performs a warcry, taunting nearby enemies to attack the user and exerting subsequent attacks. Grants a buff which boosts critical strike chance and allows attacks to benefit from increases to spell damage.
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.
Boneshatter
Attack enemies with a forceful melee strike that also hurts you. Successive uses will raise the damage dealt both to enemies and you. Stunning an enemy with the strike releases a damaging pulse. Requires a Mace, Sceptre, Axe or Staff.
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.
Soul Link

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.
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.
Vaal Cleave
The character swings their weapon (or both weapons if dual wielding) in an arc, damaging monsters in an area in front of them. Killing Blows on Rare or Unique enemies grant a buff that improves Cleave for a duration. Killing Blows on Rare Enemies also steal their modifiers for a secondary duration. Only works with Axes and Swords.
Vaal Caustic Arrow
Fires a slow-moving serpentine arrow which deals chaos damage while piercing enemies, and leaves a trail of caustic ground. Enemies standing on the caustic ground take chaos damage over time.
Vaal Venom Gyre
Creates already-caught projectiles without firing them first, both immediately and over a secondary duration. Caught projectiles spiral outwards when you use Whirling Blades and do not return. Requires a Dagger or Claw.
Vaal Smite
Calls lightning down to infuse your weapon, then performs a melee attack and causes lightning to strike nearby enemies, dealing damage in an area around each. Hitting an enemy grants an aura, giving you and your allies additional lightning damage for a duration, and additional lightning bolts with Smite. Requires a Sword, Axe, Mace, Sceptre, Staff or Unarmed.
Vaal Reap
Bloody scythes swipe around a selected area, hitting enemies with physical damage. An area of boiling blood is left beneath them for a duration which deals physical damage over time. Also gives a bonus to maximum Blood Charges for a secondary duration.

Animates multiple Melee Weapon Items and Lingering Blades to fight by your side, and transforms them into different, unique weapons. You cannot animate unidentified Weapons. Will not animate weapons with 6 sockets. Cannot be used by Traps or Mines.
Vaal Absolution

Vaal Firestorm
A fixed number of flaming bolts rain down in a spiral, culminating in the central one impacting the targeted location. They explode when landing, dealing damage to nearby enemies and leaving burning ground, which deals fire damage over time.

Increased Duration Support

Increased Duration Support is a Support gem. It will increase the duration of any effects produced by the supported skill.

Skill functions and interactions

For example this gem will increase:

  • gems must be marked with Duration.

  • The duration of the poison cloud produced by Caustic Arrow

  • The length of time that a monster will remain converted by Conversion Trapetc.

When linked to a remote skill or a skill that creates a minion, this gem will also increase the duration of skills used by the created minion or ally. For instance, if a Goatman Shaman in The Climb is raised as a spectre, the duration of the goatman's Molten Shell will be increased.

Ailments do not gain increased duration unless otherwise specified. Viper Strike and Puncture explicitly increase the duration of the ailment it applies.

This gem also does not increase the duration of Endurance, Frenzy, or Power Charges. These durations can be increased with passive skills and equipment.
