The Black crystal (reduced healing) is a permanent version of the dark crystal (reduced healing).

The crystal reduces the life points healed by an item by dealing 25% damage for every healing action. For example, if a shark (which heals 2,000 life points) is eaten, the crystal will immediately deal 500 damage.

Soul Split is not exempt from the crystal. The player will be damaged for 25% of however much Soul Split healed them.
