Throne and Freedom: How to solve the Demon's Test Quest?
To help you get your hands on the lucrative rewards, here's a complete guide to finding and completing The Demon's Test, including the solutions to every puzzle and what you'll need to get started.
The Demon's Test questline takes place in the Manawastes zone, meaning you'll need to be at least level 43 to access it. It's not part of the main campaign, so the introduction will appear as an exploration quest when you unlock the waypoint for the area.
There is no combat during the mission itself, but it helps if you are level 44 or 45, as there are many aggressive mobs in the area with attacks that cause paralysis.
