The entrance to the tomb is found through Ugdenbog in Act V after kicking off the Ashes Of Malmouth questline by talking to Inquisitor Creed in Fort Ikon. Just getting to Ugdall's tomb in Ashes of Malmouth is sort of a quest all on its own. Looking for help with builds using the new Ashes Of Malmouth mastery classes instead? We've got you covered here:
Below, we cover how to find Ugdall in the twisted bog's labyrinth, as well as your options for taking his quest or setting it aside to banish the restless spirit.
