Other points of interest[edit]


  1. In a similar fashion as MAP19, before crossing the bridge over the huge gap, you can spot several narrow but climbable steps to the left, and with the help of the jump boots you'll be able to reach the top of the mountain where you can find another pair of jump boots and a potion of excellence. (sector 959)
  2. Before entering the fortress, if you walk all around it you can find a Krater of Might to the back of it. (thing 1418 via "secret trigger" thing 1417)
  3. Once you enter the fortress, keep hugging the right wall and soon if you pay close attention you will spot a wall with a small indentation. If you look right above you, you can see a shootable switch face, which will open the wall to reveal an annihilation scroll. (sector 2252)
  4. Further back, dive into the vat of brown liquid to find a hidden porkalator (thing 1099 via "secret trigger" thing 1414)
