Part 29: How To Find the Remains of Toorum

Finding the “Remains of Toorum” in “Level 10: Goromorg Temple 2” will allow you to unlock Toorum as a playable character on your second/new playthrough.

At 7:39 minutes into the below video guide, you’ll see Toorum’s Remains can be found in the north-west caverns on the map, where you must press a small button on the wall nearby a pillar. A wall will open up (you’ll hear it) and you’ll see his skeleton on the floor, pick it up, and then revive it by throwing the remains into a save/heal crystal to unlock Toorum. Follow the video for detailed instructions.
Note: Playing as Toorum is shown in the “Ending” video below.
