This question spawned out of the following question on a Chaos Dwarf tactica thread (quoted below). @Scalenex : you have me intrigued. I was certain that the same ruling would apply to Plague of Rust as it does to Dark Subjugation. Both are hex spells that apply a permanent effect on the enemy. How should the spell interaction with the unit + character be played in the case of Plague of Rust? And if played differently from Dark Subjugation, why?
