More of a long term suggestion, since I know this was only just recently re-released.

But I think it would be neat if Plague of Scavengers could also affect Carrion Call to make it a more potent undead-only spell. I'm thinking something that defaults to off but could be toggled on when you want to fight undead, similar to how I believe Alkahest Edge works (although I think that one defaults to on).

Would that be too toe-steppy with Clerics? Too much for one spell?
