Hydrosphere Build Guide

Hydrosphere Hydrosphere skill summons a huge sphere of water that you can move around to crush enemies. While it is active, you can apply cold or lightning ailments to it. It will then pulse for a duration, afflicting nearby enemies with damage matching that ailment.

This skill gem can be acquired from level 34 and can be supported with spell, area of effect, duration, cold, orb, lightning and physical support gems. It pulses every 0.4 seconds while an ailment is applied to it. It also converts its physical damage to cold or lightning damage based on what ailments are on it.

New Skill Gems in Echoes of the Atlas

As you can see from the above example, the player is applying freeze to the Hydrosphere Hydrosphere with Freezing Pulse Freezing Pulse, and that causes it to repeatedly damage surrounding enemies with cold damage.
