I ended up giving the Bile Demon an Invulnerable Self spell, which did make him pretty powerful, but ultimately, I ended up removing it for certain reasons related to balance and gameplay.
Gameplay wise, it's actually a really bad idea to give the Bile Demon any sort of spell. The thing is, if he casts a spell, he has to stop himself to cast it. DK2 is not like DK1, where every attack animation is like 5-6 frames. Animations vary widely, and the Bile Demon has one of the slowest animations. Combined with his slow movement speed, well, basically, he won't have any chance of making it to the frontlines, and you'll have to do some annoying micromanaging to get him in front of other units to tank the hits. He's not really good for anything else in combat, so it would be better to not fault him in the area he's best at.
