You can hit the sphere with other skills to inflict Cold and Lightning Ailments (other than Chill).

    Hydrosphere

    Hydrosphere is a skill gem that creates a sphere of water, or moves an existing sphere and resets 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 at regular intervals while afflicted by an ailment, and after moving, damaging all drenched enemies in a large area with that ailment. It is classified as an Intelligence Skill Gem

    Skill functions

    Skills that hit enemies can also hit the hydrosphere. This can happen even when no enemies are around. The hydrosphere itself cannot be targeted, so skills that require a specific target and are not merely cast at a location will typically not work with Hydrosphere.

    Skill interactions

    • Brands: Brands cannot attach to hydrosphere. Activations of brands attached to other creatures can hit the hydrosphere.

    • Chain Hook: Grants Rage when hitting the hydrosphere.

    • Chaining skills: Skills can chain off the hydrosphere on their first hit. They will not chain from the enemies to the hydrosphere.

    • Curses: Hydrosphere cannot be affected by hexes or marks, even if the player applies them on-hit. However, since Hydrosphere itself does hit with its initial pulse, it can be used to curse on hit when linked with Hextouch Support.

    • Explosive Arrow: Explosive Arrows can stick into a hydrosphere and will explode as expected.

    • Frenzy: Grants frenzy charge when hitting the hydrosphere.

    • Herald of Thunder: Lightning strikes will target hydrosphere but since it is not allowed to shock it would need to be able to inflict another valid ailment.

    • Strike skills: Strike skills that strike additional nearby targets, such as those supported by Ancestral Call Support, can choose the hydrosphere as a nearby target. When combined with skills that deal area of effect damage, such as Molten Strike or skills supported by Melee Splash Support, these extra strikes can cause an area of effect overlap back onto the primary target that may increase single target DPS.

    Reflected Ailments

    Maligaro's Restraint: Shocking hydrosphere reflects the same shock on the player.

    The Fulcrum: All Cold and Lightning ailments applied to hydrosphere reflect to the player.

    Version history

    VersionChanges
    3.19.0
  • Hydrosphere can only be hit by the entity that cast it.
    • 3.17.0
  • Hydrosphere now deals 37 to 56 Physical Damage at gem level 1 (unchanged), up to 510 to 765 at gem level 20 (previously 356 to 533).
  • Now has 110% Effectiveness of Added Damage at all gem levels (previously 80%).
  • Changed Hydrosphere to have a one second cooldown before it can be hit again. This maintains the ailment mechanic on Hydrosphere to still allow for some special skill interactions but is no longer such a significant single target damage multiplier for so many skills.
    • 3.13.1e
  • Fixed a bug where '''Hydrospheres''' couldn't be Shocked or Frozen when using Elemental Hit as a Ranged skill.
    • 3.13.0
  • Introduced to the game.
