Decaying Blast is an Expert level Destruction Spell added by the fourth plug-in Spell Tomes.

Known locationsEdit

As with all Spell Tomes, Decaying Blast spawns randomly depending on multiple factors such as the Hero's level and spell level.

However, for the best odds of finding a Spell Tome, the Hero can search boss-level chests in Necromancer and Conjurer lairs.
