We play a mainly pathfinder game (occassional and as time goes on fewer feats from 3.5) and we still keep coming across things that have changed between 3.5 and pathfinder.
Casting a spell triggers an AoO (unless you cast on the defensive) but does touching an ally to deliver the spell trigger as well? A pathfinder RAW answer would be good. I am sure in 3.5 it did but cannot find anything in pathfinder.
I have found something that says if I use a full round action to touch upto 6 ally it does trigger (if you can fit an enermy in that ruck) but how about just a standard action and just one.
