Way of the Iron Fist

This is subclass that refocuses the monk away from dexterity and onto strength. I tried to make something that would make a strength focused monk viable rather than an undertaking

Iron Body

Starting when you choose this tradition at 3rd level, whenever a monk feature would have you use your dexterity modifier you can choose to use your strength modifier instead.

Additionally you can choose to expend one Ki point as a reaction to gain resistance to all damage types except psychic until your next turn.

Shattering Strikes

Whenever you make an attack with your unarmed strike you can choose to add your proficiency bonus to the damage roll. 

Additionally when you hit an enemy with an unarmed strike you can expend 2 ki points to deal your martial die in additional damage and the target is knocked prone and cannot stand up until the start of your next turn.

Immovable Stance

You have advantage on checks and saves to resist being grappled, restrained, forcibly moved or knocked prone.

Beginning at 11th level, when you are hit by a melee attack as a reaction you can expend 2 Ki points to reduce the damage by 2d10+your strength modifier+your monk level. If you reduce the incoming damage to 0 you can make an unarmed melee attack against the target if they are within range.

Menacing Aura

At 17th level, you radiate an aura of pure menace. Enemies making a melee attack against you must succeed on a wisdom saving throw, DC equal to your strength modifier+your wisdom modifier+your proficiency bonus,  if they succeed they have disadvantage on the attack roll. If they fail they become frightened and must use their action to move as far away from you as possible.
