Silver Blast is a monster-only spell which behaves like a holy silver Fireball, creating an unavoidable 3×3 explosion around whichever tile it targeted. Although it's capable of dealing tremendous amounts of damage, it is designed to only affect chaotic and evil targets, so most characters will resist the majority of it. After base damage is calculated, all targets then have that damage reduced to only 5% of that amount for each acquired mutation they possess (innate mutations do not increase the damage dealt, but demonspawn mutations do). Shapeshifted monsters and characters will always take full damage, while undead characters and followers of chaotic gods always take at least 33%.
