There seems to be a bug or bugs with hell power. CMB may be involved, but the bugs also transcend cbm.

A. Caster is a 2/2 vampire.

1. opponent casts a spell.
2. Vampire casts hell power. Fatigue 14. Only 2 blood slaves are consumed
3. Vampire immediately casts Summon Imp. (it seems out of turn) Fatigue is now 34. 2 blood slaves consumed.
4. Opponent casts a spell.
5. Vampire casts Hellbind heart. Fatigue is now 84. 2 blood slaves consumed.

These exact fatigues have been repeated a couple of times.
Vampire is never horror marked. No horror ever appears. Vampire gets no bonus to any physical stats.

Spell Vanilla CBM
Hell power B2 F300 B1 Fat 300
Summon Imp B1 F100 no change
HellBind B2 F100 no change

So I guess
A. I don't understand how the fatigue is 14 after casting Hellpower.
B. I don't understand how the summon spell is immediately cast.
For the fatigue to be 20, the only way for that to happen is for the caster to be a 5th level caster, or a boost of three (not 2 as in the manual). So, I'll presume that what hellpower actually does is give you an immediate boost on casting another spell.
C. I don't understand why *2* blood would be consumed for reinvigorate.
