Obviously just about any weapon would be better than fists for a character that's not trained in unarmed combat, but I'm curious as to what stats I should give PC's when forced to fight unarmed (perhaps their weapons were stolen or they were imprisoned). I'm looking for a little more than just numbers though to add a bit more flavor, like some bonuses against small creatures that might also let them push or pull them.
I've never created my own stats before, but here's my rough estimate:
Fists (weapon) <> at will attack: Melee 1 (one creature); +5 vs. AC or Reflex, whichever is greater Hit: 1d4 +2 damage against a small creature and push/pulls target 1 square. 1d4 damage otherwise.
Does this seem to meet the requirements for how unarmed melee should work? What stats have you successfully used for unarmed combat?
