IMHO these spells do small damage to undead, comparing it to consumption of mana and lag they create
Few examples:
Spellpower: 35 (dunno if these count on prayers)
Cure critical (20 mana) vs Juju zombie (from maus)

You draw upon the powers granted by your god.
The Juju zombie is seared by the positive energy!

Second cast
You concentrate a moment and pray to your deity.

As you can see, spell damage varies but its roughly the same with few exception on heal but those are rare.
Maybe just change resistance on undead would do the trick? (Something is certainly off)
BUGImbue regeneration cast on undead doesn't check svs and it's not making mob aggressive.
SUGGESTIONWould also like to make a little suggestion, make imbue regeneration combat spell,
and let it damage undead with positive energy as it heals mortal men evry few seconds.
