Band of Justice

"I never sleep, and you most certainly won't either when I'm through with you." 

This dwarven ring is forged from dark grey, nearly black steel, inscribed with dwarvish writing which translates to "The hand which always falls". As an action, you can cause the ring to become invisible on your finger, or to glow with dim light for five feet. 

Unneeded Gaze. You have blindsight for thirty feet. 

Speak the Name. You can cast the locate creature at will. When you cast the spell in this way, you must know the true name of the creature, and speak it as apart of casting the spell. While targeting a creature with this spell, they cannot have advantage on attack rolls against you. While you have this spell active, you have advantage on perception and survival checks. 

From Outside In. Whenever you deal damage with a melee attack, you deal an additional 1d6 psychic damage. Whenever you hit a creature immune to psychic damage with a melee attack, they take 1d8 force damage.
