Followers of the Way of the Steel Heart are the embodiment of pushing oneself the their limits. They train to bring themselves to their upmost limits and hone their bodies and minds to endure any path they choose in life no matter how difficult.(This is just a subclass I made for my own enjoyment taking things from other classes not a serious publication)

Hardened Fist

Starting when you choose this tradition at 3rd level, you can manipulate your opponents body using different blows. Whenever you hit a creature with one of the attacks granted by your Flurry of Blows, you can impose one of the following effects on that target:

• It must succeed on a Dexterity saving throw or be knocked prone.
• It must make a Strength saving throw. If it fails, you can push it up to 15 feet away from you.
• It can’t take reactions until the end of your next turn.

Body of Steel

At 6th level, you gain the ability to heal yourself. As an action, you can regain hit points equal to three times your monk level. You must finish a long rest before you can use this feature again.

Tempered Will

Starting at 11th level, your willpower can keep you fighting despite grievous wounds. If you drop to 0 hit points while having ki points and don’t die outright, you can make a DC 10 Constitution saving throw. If you succeed, you consume 3 ki point and drop to 1 hit point instead.

Each time you use this feature after the first, the DC increases by 5. When you finish a short or long rest, the DC resets to 10.

Icon of Strength

Starting at 17th level when you attempt to hit with an unarmed strike, you can spend 10 ki points to on a hit force a critical or on a miss force the attack to hit with normal damage. On a natural critical damage is multiplied by 5 and the target must make a dc 12 constitution saving throw or be dazed and unable use reactions until its next turn. This ability can only be used once per long rest.
