1. Go to Fortress of the shield (the outside area) at day
2. Enter one of the ruins (to the left or right of the mainpath to the tower)
3. Make sure the torches inside the ruins/crypts are not lit
-> Observe that even though it is dark inside, and the torches are off, the undead count as "in bright light" and receive 10 damage per round. No need to light torches.
