Decaying Heart can be used in the Tailoring and Armouring professions to grant other ingredients touching it -100% effectiveness, nullifying their effect (ignoring other meta-ingredients). Meanwhile, ingredients not touching the Decaying Heart receive +75% effectiveness.

  • A good use of a Decaying Heart would include making it touch ingredients that add durability, as effectiveness does not affect durability. To use this tip to its fullest, place a Decaying Heart on any corner of the crafting grid.
  • When used in a corner spot, Decaying Heart allows nearly full ingredient power (3 slots at +75% each is the equivalent of 5.25 slots of power, provided your ingredient combination works with this) and also frees up two spots for durability boosters.
  • Decaying Heart can be used in conjunction with Obelisk Core or Major's Badge to give effectiveness boosts to flipped ingredients.
  • Combining Decaying Heart with a Bob's Tear allows for two ingredients to reach +100% effectiveness, allowing mana regen and steal ingredients to have doubled effects.
