Well. Good luck. But I will prefer a mod which fixes tens of problems (including Necromancer) and has long history of the development.

The balance mod is a rat king of outdated, bad, and unclean edits where every comment is asking about compatibility patches because it wrecks far too many packs in ways it can't even keep track of. This mod is precise and concise.

At best, the balance mod is a pile of spaghetti garbage that only makes the game easier; the point here is to make the game harder. Not to mention that the balance mod does nothing this mod does, or that the balance mod fails to hinder snowballing possession on its own anyway.

Install Balance mod.
