Strange creatures are a weak type of custodian stalker encountered within the Stalker Den during the Shadows of Custodia quest. Three of them ambush the player when they attempt to rescue Antos.

The creatures have the same combat stats and drops as juvenile custodian stalkers, but slightly reduced hitpoints.

Although it is not normally possible to be on a custodian stalker slayer task before completing the quest, the creatures do count for the task.

Drop rates are estimated based on 40,564 samples from the Drop Rate Project, unless otherwise cited.
