  • While it is crafted from the Blood Pact, it does not give enemies the ability to perform critical strikes on the player. In compensation, the player's maximum health is increased by 10% rather than doubled.
  • If the player dashes through an enemy using a shield (such as the Elysian Aegis or Asgardian Aegis), the effect of halved contact damage will be put on cooldown despite the fact that no damage was taken.
  • While it is equipped, Healing Potions will have their tooltips updated to reflect on their boosted effects.
  • The health potion increasing effect stacks additively with that of the Blood Pact.


  • Its name may be a reference to the memetic phrase "Blood for the Blood God", from the Warhammer 40,000 game series.
  • It can be considered the counterpart to The Amalgam.
