Hellfire Burst

Version 0.17: This article may not be up to date for the latest stable release of Crawl.

Hellfire Burst is a monster-only spell which smite-targets you or an ally with a 3x3 burst of hellfire, dealing unavoidable, AC-ignoring damage to all affected tiles. Damage varies based on the recipient:

Damage to player: 3d15 (3-45)
Damage to player allies: 5d7 (5-35)

Deep dwarves will take slightly reduced damage due to their damage shaving, and anything with hellfire resistance is entirely immune to its effects.
