2. Eroding Blast

If successfully cast, pick 1 terrain feature wholly within 18" of the caster that is visible to them. Roll 1 dice for each model within 1" of that terrain feature. For each 5+, that model’s unit suffers 1 mortal wound. In addition, until your next hero phase, that terrain feature has the Deadly scenery rule in addition to any other scenery rules it may have (core rules, 28.1.3).
