question :
you have 19 reinvigoration if i counted right .
the heart though gives you a chestwound ( + 5 encumberance iirc ) .
a demonbred has base encumberance of 5 too .

so you get 9 net reinvigoration each turn right ?

further question :
your fire brand makes fire damage .
if my sc is 100% fire immune he shouldn't suffer any damage right ?

so what with a standard ice devil / bane lord with a life leech weapon and the base gear like pendant of luck , boots of flying , jade armor etc ?

just scripted to attack immediately .
then you have phonix pyre up but are probably 2 times hit and suffer already quite nice fatigue .

i think the standard ice devil / bane lord should have quite good chances to bring you to 100 fatigue sooner or later .
i don't know how much damage you suffer though from the phönix pyre explosion but i think not too much .

i have not too much knowlegde with blood vengeance yet but a standard ice devil / bane lord with amulet of antimagic etc has a pretty high mr too so the blood vengeance effect shouldn't hapen too often .
