PoE2 skill gem

Volcano

Uplift a volcano from the earth, damaging enemies standing on it and releasing a spray of molten Projectiles. While the volcano persists, Slamming it will cause another Projectile spray. Channelling this Skill for longer makes the initial eruption more violent, but does not affect subsequent Projectile sprays.
