Hammurabi

Enduring Punishment Whenever you deal damage to a creature, that creature can’t regain hit points until the start of your next turn.

Law of Retribution

When a creature you can see hits you with a melee weapon attack, yyou have advantage on the next attack roll you make against that creature before the end of your next turn.

Forbid

If a hostile creature you can see uses its action to attack or takes a legendary action or a lair action, you can use your reaction to intercede, causing the creature to lose the action. Once you use this feature, you can’t use it again until you finish a long rest.

Trait: Maimed

While bound to Hammurabi, you are missing multiple fingers, several teeth, and an eye—all gouged out as recompense for past crimes. You are immune to the following conditions: blinded, deafened, exhaustion, paralyzed, poisoned, and stunned. If a creature targets you with an effect that would impose one of these conditions on you, you can use your reaction to cause that creature to be targeted by the effect instead.

One of the first great kings of humankind, Hammurabi set forth mortal law on a stone obelisk. Today, his vestige grants binders the authority to judge others by the first laws and inflict their cruel punishments. 

Legend

Mortals have always been judged by the whims of the gods when they passed onto the afterlife, but it was not until the early kings of mankind that mortals passed judgment on each other. Hammurabi, king of a long-forgotten province, beseeched the gods for laws that would solidify his rule with exacting authority. The gods granted his plea and delivered an obelisk inscribed with every conceivable crime and punishment to his kingdom.
These primeval gods believed in order above such petty qualms of good and evil. After all, they carved all of creation from  sprawling chaos and struck a mathematical equilibrium; they did not take such balance for granted. As such, their laws were perfect counterbalances: an eye for an eye, a bone for a bone, a hand for an errant strike, and so on. Brutal as they were, the people of Hammurabi found them effective. 
However, as Hammurabi would learn, no man is above this law. As all people could read the obelisk’s code, some came to their king with grievances enforced by the law. In recompense, Hammurabi lost his own eye, fingers from each hand, his teeth, and the hair from his head, and suffered many other punishments for his fleeting crimes as king. Even his vestige is maimed and broken, a symbol that truly fair punishment endures even after death.

Ideal

While bound to this vestige, you gain the following Ideal: Eye for an Eye: "I strive for absolute equity in all things, and will go to extremes to ensure fair recompense for all deeds."
