I just respecced and am having a confusing issue with my summons.

I have 24 points in demonic mastery, which should clearly allow me 3 summons.

I have a bound demon

I go to summon a tainted, he dies between 1-3 seconds later

If I summon a tainted and defiler, both of them die.

If I summon two defilers, both of them live.

I feel like I'm taking crazy pills here and can't figure out why the tainteds won't stay alive. Fresh game, no consumes.

Flickering flame aura kills the tainted, one mate wrote about it.

Oh that's fun. Thanks for the insight, I guess I'll need a new hat!
