The Forgotten Soul is a red coloration of the Lost Soul, found in the Volcanic Spirit Cave, found under the Volcanic Islands.

The forgotten soul will attack anyone who attempts to enter the cave. When fully armored with iron or steel the forgotten soul will deal minor damage. It is has very little resistance to attacks since even a rock can deal 5 damage to it, killing it with 6 hits. The forgotten soul has no drops. but the experience reward is great, making the forgotten soul a good experience source as they respawn rather fastly.
