Wishbone
Paladin Radmaster
I would note that they played Pathfinder pre-stream (sans the initial Birthday one-shot which was 4e) and also it seems to me like Sam knows what his class/race allows but often purposefully avoids certain things, he notably has said the Halfling luck "seems dumb" on a few occasions
I don't remember exactly when he said that, but it could always be Sam razzing Liam over always using the Luck feat in Campaign 1 much to Matt's chagrin.
