The potion of healing restores 2d4+2hp to the character who drinks it, provided the character does not exceed his or her original hit point total. The effect is permanent.
Typically a potion of healing will contain 1 dose, but larger flasks of 2-5 (1d4+1) doses are occasionally found. It takes one segment to drink a potion of healing and it will take effect 2-5 (1d4+1) segments afterwards.
Variants:
The potion of extra-healing is precisely as a potion of healing except that it restores 3d8+3 hit points. It may be partially consumed, restoring 1d8hp per third of the liquid drunk.
