OH, yeah, Law Devotion is way better in this environment. I'll definitely train for that. Kind of wanted the Envy domain this next level, but I guess that one is better (I've got debuffs out the wazoo already).
Death Devotion has been pretty kick ass, though. It nearly always works. Two shenanigans I've used:
1. Debuff enemy at range. Cast True Strike from Domain slot. Channel Death Devotion into club. Throw club and give a negative level. (The feat doesn't require a melee attack, just a melee weapon).
2. Debuff enemy with high AC. Channel Death Devotion into Gauntlets. Initiate grapple vs. touch AC. Give negative level. (The feat doesn't require damage, either, just a successful attack.)
I'll retrain it away when its clear that fort saves are way too high to use it.
