The achievement "demon hunter" isn't triggering from picking up a demon crystal. After looking into the triggerlist of picked up items I saw, that it's missing. Also the bazooka achievement shows the unlocalised name/description. I am using bloodmagic 13.3.11.

shouldn't the summoned demons count for demon slaying? (not the convocation demons)

No...the target is the demon village

ah ok

But I did just add an achievement for summoning demons :D

Demon Hunter is obtained by slaying a demon

And I'll fix that Energy Bazooka achievement!
