Bare Knuckle Boxer

Starting when you choose this fight club at 3rd level, your unarmed strikes score a critical hit on a roll of 19 or 20 on the d20.

Cross Counter

Also starting at 3rd level, you can block the brunt of an attack and launch one of your own in the same fluid motion. When you take damage from a melee weapon attack, you can use your reaction and spend 2 moxie points to reduce the damage by 1d10 + your Strength modifier + your pugilist level.

If you reduce the damage to 0, you can make an unarmed strike or pugilist weapon attack against a creature within range as part of the same reaction.

One, Two, Three, Floor

Starting at 6th level, when you use your bonus action to use the Old One-Two and hit the same creature with both attacks, you can spend 1 moxie point to make an additional unarmed strike against that creature as part of the same bonus action. If you hit, the creature is knocked prone in addition to taking damage as normal for your unarmed strike.

Float Like a Butterfly, Sting Like a Bee

Starting at 11th level, when you reduce damage from an attack to 0 and successfully hit an enemy creature using your Cross Counter feature, you regain 1 expended moxie point.

Knock Out

Starting at 17th level, when you hit with an unarmed strike or pugilist weapon, you can spend 1 or more moxie points to try to knock out the opponent instead of dealing damage. Roll 3d12, plus an additional 2d12 for every moxie point spent after the first, and add your pugilist level to the result. If the total is equal to or greater than the creature’s remaining hit points, it is reduced to 0 hit points.
