"We are not placing our stone here, then? Mm, then the tides drive us to resign."

Bearing of a Salsu
Whenever you hit a creature with a melee weapon attack, you gain 1 stack of Poise. After gaining this Poise, roll a separate d20. If the result of the d20 is equal to or less than your Poise stack, you deal additional damage equal to your fighter level. When this extra damage is triggered, your current Poise stack is reduced by (10 - your proficiency bonus), this cannot reduce your Poise below 0. You can have up to 30 stacks of Poise.

At level 10, you may make 2 weapon attacks against the creature that hit you instead of 1.
At level 15, you may make 3 weapon attacks against the creature that hit you instead of 2.

Yield My Flesh
Before you make an attack against a creature, you may declare the attack to be a 'Clash' instead. During a clash, both you and the target make attack rolls against each other, applying bonuses to attack rolls as normal. The creature with the higher attack roll wins the clash.
If a tie happens, the clash starts again. For each tie, the eventual winner's attack deals an additional 1d4 damage.

If you lose the Clash, the target immediately makes one attack against you using the attack roll it made for the Clash. If you have more than 15 hit points when the attack is made, it cannot reduce you below 15 hit points.
After you win a clash, your attacks against the creature you clashed with deal an additional 1d6 slashing damage until the end of your turn.
If you lose a clash, you gain 'Yielded Flesh', which allows you to use a future feature. You lose Yielded Flesh at the end of combat, and can only have 1 instance of Yielded Flesh at any given time.
