merciful weapons do an extra 1d6 damage which can, but doesn't have to be subdual. It's better than flaming, or frost IMO.
Did I mention it's a +1 adamantine, merciful falchion with quicksilver and ghost touch weapon alchemical capsules sheathed in a sacred scabbard. Improved Critical at level 8.
Oh yeah baby:
DR/adamantine check
DR/magic check
DR/good check
Incorporeal no problem
DR/silver check
Crit on a 15-20 with an auto confirm against evil creaturs.
Also, Pro Evil only hedges out compulsion from evil people or creatures or at least that's the way we play. Also, it doesn't suppress mental compulsions in effect it only suppresses those that are cast on them after the Pro Evil is up. The spell is worded quite poorly for that distinction, but I think that's the way to go as personally I feel it's wrong to let a 1st or 2nd level spell shut down so many higher level ones.
