Bead
Twice per room, when the owner ingests (consumes via the mouth) any kind of healing item, the owner heals +3 HP.
To be compatible with Bead of Greater Binding, the ingested item must restore HP expressed as an integer, not a variable such as “half” or “all.” Items which bring the dead back to life are not affected by this item.
The wearer of this item may not equip a Bead of Binding.
The wearer is able to affect critical hits creatures that are normally immune to critical hits (e.g., constructs, oozes, plants, undead, etc.) It also allows rogues to perform a sneak attack on creatures that are normally immune to being sneak attacked.
