One big bubble, many puddles on impact. Bubble covers a wider area than the Thrower in a single cast, making it the go-to Acid spell for horde situations where you need corrosion spread across multiple targets fast. Less precise than Geyser and less spammable than Thrower, but it blankets a room faster than either.
Strategy
Throw it ahead of an approaching wave to pre-saturate the floor with puddles. The spread pattern means at least some of the puddles will land under key targets even if your aim is off. Excellent before rushing in with a Shotgun.
Strengths
Covers the most ground per cast in the Acid school
Fast corrosion setup against multiple enemies at once
Forgiving aim requirement due to burst spread
Weaknesses
Individual puddles deal less sustained damage than stacked Thrower coverage
