Pugilist

The Pugilist is an odd group to classify, ranging from bare-knuckle boxers in underground fighting rings, to mercenaries more trained with their hands more than their daggers, to even the loftiest knights whom feel more at home with the iron of their gauntlets than their swords.

Fistful of Copper

You may grab one non-weapon object from either your Inventory or within your reach as part of your Attack whenever you take any variety of Improvised Attack Action. (Like grabbing a vial of Oil or a Brick from your bag as part of the Attack Action as an Improvised Weapon.)

Stopped Short

Whenever you move an enemy with your attack, like from the Shove Action or the Crusher Feat, and that enemy is stopped by an ally, wall, or otherwise impassable terrain, that enemy takes 1d6 Bludgeoning Damage for every 5 Ft they would have moved if uninterrupted.

Brace

As a reaction when you are hit by an attack and not holding any weapons or shields, you can raise your arms into a defensive stance. Until the start of your next turn, you have a bonus to AC equal to your Strength Modifier, including against the triggering attack.

Bob and Weave

When you are holding no weapons or shields, you gain the following benefits.

If you aren't incapacitated, you can add your Strength Modifier as a bonus to any Dexterity saving throw you make against a spell or other harmful effect that targets only you.

If you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you can use your reaction to take no damage if you succeed on the saving throw, weaving between and bracing against the source of the effect.

Fight For Your Life

Starting at 18th level, your sheer grit can delay the grasp of death. Once per turn when you make an attack, you regain hit points equal to the damage dealt by your attack, if you have no more than half of your hit points left. You don't gain this benefit if you have 0 hit points.
