Whenever I cast the demon summoning spells (Heptagon, Blood & Furor), the demon always ends up turning on my party eventually. Will this ever change? Summoning a demon is cool and all, but an utter waste of AP and time if it's unreliable like this.

I don't know. I've seen Blood & Furor work with newly generated auto-leveled Demonologists in the third game. The piddly weak, weapon-immune demon just sat there and ate a facefull of Ogre every round. That is, at around 10 points in the skill. Never seen it even begin to work in the opening battle of the second game.

I haven't played it in a long time, but I think skill level maybe affects things. Here's a post of someone saying something similar.
