- "Murtlap Tentacles are known for their healing properties."
A Murtlap tentacle is a rare potion ingredient that can be obtained from the growth on the back of a Murtlap. When a Murtlap tentacle is eaten, they heighten resistance to various dark charms, but an overdose has the side-effect of purple ear-hair. They are also known to possess healing properties and are used as an ingredient in the brewing of the Murtlap Essence.
