Overview

How it plays

The Acid school's big curtain call. Rain calls down sustained acid across a wide area for its full duration, layering corrosion on everything caught underneath. It's not subtle and it's not fast to recharge, but nothing else in the school covers this much ground continuously.

Strategy

Drop it on objectives, doorways, or boss arenas where you know enemies will be forced to stand still. The sustained damage is most effective when targets can't leave the area. Combine with Contagion beforehand to maximize the debuff overlap.

Strengths

Widest area coverage in the Acid school
Sustained damage over duration rather than one burst
Extremely effective on objective-based encounters

Weaknesses

Longest cooldown in the school
Moving enemies can walk out of the rain area
