[[Category:Encounter ]] [[Category:]] Corrosive ruin was an evocation spell used by some swordmages of relatively low experience and power. When cast corrosive ruin shot a spinning spray of deadly acid out from a swordmage's blade into a nearby area of fifteen feet in diameter, searing any creatures caught within the blast zone. The spell was relatively easy to cast and could be recharged with a rest of a few minutes or more.
