Yseria

Equip: Your spells have a chance to destabilize the void energy, releasing a corrupted fragment. Retrieving a fragment briefly infuses you with its power, increasing your Intellect by 42 for 15 sec.

Use: Charge the crystal to summon a rift that draws power from nearby enemies, inflicting 13,991 Shadow damage over 6 sec. When the rift collapses, its drawn energy returns to you to increase your Intellect by 4 for 20 sec, further increased for each enemy struck. (2 Min Cooldown)
