Charms can only be equipped and unequipped by using a bench.Picking up the charm will automaticallyВ take The Knight out of the cave and permanently closing its walls. It is important to take note that you must not take any type of damage, or rest at a bench since you will lose the Lifeblood Masks you have collected - once you have made it inside the cave, make sure to (FIRST) pick up the Arcane Egg, followed by the charm. Players can equip Lifeblood Heart, Joni's Blessing, and collect Lifeblood Masks from LifeseedsВ scattered around the map in order to gain the required number of Lifeblood Masks. Acquisition: To obtain this charm, first, you will need 15 or more Lifeblood Masks equipped in order to unlock the wall of a cave that is located on the left side of The Abyss.The addition of Lifeblood Masks helps with increasing The Knight's health and durability, however, if The Knight takes any damage, players will not be able to recover it with Focus. LifebloodВ Core is a charm that provides The KnightВ 4 Lifeblood Masks when resting at a bench. 'Contains a living core that bleeds precious lifeblood.' Charms require Notches and can only be equipped and unequipped while having The Knight sit on a bench. If I recall correctly, it had to do something with the blue liquid (it's called lifeblood, right) I got all 3 spells. I think I might be able to unlock it later. Over on the left side of said 'tunnel', there's a door. These charms are special items that provide The Knight buffs that will help with both traversing Hallownest and battling its foes. Below the Ancient Basin there's a huge drop leading to the Abyss. Lifeblood CoreВ in Hollow Knight is one out of the 45 Charms that is found in the game. When resting, the bearer will gain a coating of lifeblood that protects from a large amount of damage.
