User blog comment:Corelie/Ambiant Demonic Energy Corruption in D&D Pathfinder/@comment-26869585-20150902185341

Its not actualy permanant it can be removed via a spell such as restoration and lesser restoration. Still damage to your SE is serious mather especialy if its demonic energy. I did think about doing this as a Wisdom drain but a Wisdom drain wouldnt be as deadly

(if it would happen wisdom drain would be less of a shore to deal with i could actualy convert it to that)
