Brawler

When you choose this sub-class, it doesn’t take away your ability to use weapons, but it would be better not to if you want the full effect of being a brawler. When you pick this , you gain a +1 attack and damage bonus to unarmed strikes, this increases to +2 at level 7, and +3 at level 15.

All in the arms

Starting when you choose this path at 3rd level, Any unarmed attack you make will be made with a +1 bonus to damage and attack. This is increased to +2 at level 7, and +3 at level 15.

No Escape

Beginning at 6th level, If you grapple anyone, they roll with disadvantage to escape, when you hit anyone, their speed is decreased by 10 for that round. If you are raging, your speed increases by 10, and you cannot be frightened.

Ferocious hitter

Beginning at 10th level, While raging you gain an extra attack to grapple or use an unarmed strike against an enemy. If you grapple him, he takes 1d4+ you unarmed strike modifier bludgeoning damage because of just how hard you do it.

Broken Bones

Starting at 14th level, Your physical strength has become so powerful, that while raging, your unarmed strikes go through resistances. If the target has bones, you can use your attack to hit so hard it debilitates your foe. You can do this as much as your strength modifier. People hit by this must make a constitution saving throw (prof + 8 + str mod), or be incapacitated for their turn (1 round). This also halves their running speed, reduces their constitution, dexterity, and strength scores by 5 (to a minimum of 5). A person trained in medicine can make a dc 15 medicine check to end these effects early. Every short rest, you can make a constitution check throw (dc 15) to end the effects. After a long rest, you make that constitution check with advantage, and after a week, the effect just end. You regain all uses after a long rest.
