Lost souls are roaming spirits that may be found during the Anima Islands D&D on the island with spirits and corrupting tentacles. When players enter a grave on the bottom part of the island, they will be shifted to a different realm and be able to see a lost soul. Players can capture it into their relic of life, making it into a relic of life (charged).
- Originally they were part of the Tuska Comes event.
- Lost souls are virtually identical to the weak ghost from the 2014 Hallowe'en event, except they are orange in colour.
- Lost souls can be right-clicked and examined even while not visible from the normal realm.
