Sacrifice pit ability question

With the sacrifice ability I was wondering if
1. The acolyte can be any unit and
2. If it can be changed into any unit other than shade

Tnanks

Im not sure it can be changed, its most likely it can but what i suggest is basically just edit the shade and the acolytte units to waht u want.

then if u need an acolyte or shade just base them off the normal ones

sacrificial pit + acolyte are hardcoded.
