A large ruin in Welwyn Valley, north east. Contains Undead. (Quest Related).
The Burial Chambers in Epiblepo have many switch operated doors on very tight timers. You will need to figure out the best order in which to activate them and move with haste to get through the doors.
Tip: This would be a good place to use your party members to your advantage. Move them up one by one through the doors you open and get them to wait on the other side where the second switch will always be located.
