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

Conversion

The gem's advanced description specifies (If both conversions apply, each will convert 50%). In other words, if affected by both a Cold (excluding Chill) and Lightning Ailment, it will convert its Physical damage to 50% Cold and 50% Lightning damage.

You can only have one Hydrosphere at a time; whenever you recast the skill, it will either cause the sphere to pulse and refresh its duration in the same location, or the existing hydrosphere moves to the targeted location without pulsing and the duration is refreshed. Refreshing or moving the hydrosphere will not affect the pulsing behaviour from inflicting an ailment on it.

Critical strike

  • Critical Strike: Because Hydrosphere is only a single spell, its critical strike chance is only rolled once. If it crits, the first hit including every pulse after will be a critical strike. If it doesn't crit, none of them will be.

Repeat

When Echoed, the placement of the sphere will be repeated, but the pulses will always count as a final repeat, making it synergize well with Plume of PursuitPlume of Pursuit

Energy Shield: (64-92)Requires Level 64, 73 Int(30-20)% reduced Cast Speed

On-hit mechanics

Skills that hit enemies can also hit the hydrosphere. This can happen even when no enemies are around.[1] The hydrosphere itself cannot be directly targeted, so skills that require a specific target (e.g. Flicker Strike) and are not merely cast at a location will typically not work with Hydrosphere.

A Hydrosphere is considered a solid entity; it can block narrow passageways or bridges unless an entity has Phasing or can blink over small obstacles. Projectiles that hit a Hydrosphere will consume a hit and cause any relevant projectile behaviours to occur. It has a hit internal cooldown of 1 second that cannot be modified by increased cooldown recovery rate.

Enemies cannot hit your hydrosphere.[2]

Ailments inflicted by the orb's own damage can proliferate, but ailments inflicted on the orb cannot.

Skill interactions

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

Version history

Version Changes
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.
