Ring

Very Rare Requires attunement by a Blood Hunter, Hemomancer, or Wizard (Necromancer)

This ring is made from dark steel with few decorations except a singular small ruby which seems to be giving off a faint light that synchronizes to its wearer's heartbeat in a fight.   Bloody Desperation. As a bonus action you can choose to halve your hit point maximum, and regain an amount of hit points equal to half your original hit point maximum. While your hit point maximum is reduced in this way, you are treated as bloody, and when you would become bloody with the hit point reduction, you instead become very bloody.   If your hit point maximum can not be reduced, you instead heal up to half your hit point maximum and gain 2 exhaustion points.   Once you have used this ability, you can’t do so again until you have finished a long rest, at which point the reduction to your hit point maximum from this ability is restored.   Greater Constitution. Your Constitution score is increased by 2, to a maximum of 30, and you become immune to the Chilled condition while wearing the ring.
