Upon use, an Undead Hunter Charm is thrown at the ground, releasing a white cloud that affects anyone that walks into it. The cloud persists for a short duration, meaning targets do not have to be hit directly for it to function.
The main effect of Undead Hunter Charms is their ability to temporarily prevent opponents from healing with Estus or Ashen Estus Flasks. The effect lasts roughly 25 seconds. Other forms of healing, such as Siegbräu or miracles, can still be used while under the effect of a charm.
They may also be thrown at Mimics, forcing them to go into a lethargic state after which they can be looted without risk of dying. Additionally, the Mimic has a chance to drop a Symbol of Avarice every time it is put to sleep by a charm.
When thrown at glowing-eyed skeletons, it will prevent them from reanimating, allowing them to be killed the first time around.
