- There is a chance that this boss will not spawn during the Ruins of Surmia mission as he shares spawn locations with 2 other bosses (Hurl Foulspine and Fester Fang).
- This boss is also trapped behind the wooden charrgate near the location of Breena Stavinson in Ruins of Surmia. You can't reach him in any way and he therefore can't be killed.
