I've been kicking around ideas on using Hex Strike, but it's hard to beat the foundation provided by a Hexcrafter. I know from the FAQ that you can spell combat with unarmed strikes, but that does leave a few questions.
(1) Can you use your arcane pool to enhance a punch that can deliver a Hex Strike? It's not clear to me if you can straight up enhance your unarmed strike. I know you could enhance a cestus, but then it's not clear to me if a cestus-punch can deliver a hex strike.
(2) Order of operations. Let's say I have Enforcer and Hex Strike (Slumber). I punch somebody, doing nonlethal damage. Enforcer lets me do a free action intimidate on them, while Hex Strike lets me do a swift action slumber hex. Can I choose the order that these two things fire off in? If not, which goes first?
Same question, but now the bad guy is already shaken and I'm wearing a Cruel Amulet of Mighty Fists. Does he become sickened before I deliver the slumber hex? On a related point, if I have a cruel amulet going and the slumber works, do I gain temporary HP?
(3) Enforcer shenanigans. Say I have a Frostbite spell going with at least one charge left. I use a wand of Blade Lash to make a trip attempt against a bad guy. It succeeds. Since I touched him while holding a charge, he takes Frostbite damage. Does this trigger Enforcer and let me intimidate him?
