Way of Endurance

You are well trained in the means to keep going, even through all the hits you take.

Conditioning

Starting when you choose this tradition at 3rd level, you can instead use your constitution modifier to unarmed strikes and armor class.

Ki-Bulk

Your training has made you become a phenom of hit-taking.

As a bonus action, you can spend 3 Ki to gain your Monk's hit-die maxed (8) + your Constitution Modifier + Proficiency in temporary hitpoints. You can do this once per short rest.

When doing this, you reduce your hit-die pool by 1 until your next long rest.

Healthy Upkeep

At 6th level, you gain +5 to Constitution Saves.

Stillness of Form

Beginning at 11th level, you are a titan of form.

You can use the Stillness of Mind feature to undo any condition.

You can also spend 5 Ki to remove a point of exhaustion.

Tempered Body

Your body has been perfected to be like that of Adamantine steel.

You are immune to critical hits and have resistance non-magical bludgeoning, piercing, and slashing damage.
