Drezen Fortress Puzzle Solutions
Drezen Fort features two Sword of Valor banners including the real and fake one. The banner in the west hall is the fake one that it you touch it, it will summon a large group of demons and fireballs and trigger the trap. The room in the south contains the real banner. You need to fight with a large pool of corpses and you have to use the secret passage that is revealed by “Yaniel” to reach there.
One of the solutions to Drezen Fortress puzzle:

(You need to rotate the sigils to deactivate the traps, be careful once traps are deactivated three demons will appear to attack you)

If you want to unlock the third Mythic Level, put the Valor of Sword Banner on the wall. There are multiple paths, so you need to decide which Mythic path to choose. These mythic paths include Gold Dragon, Swarm-that-walks, Legendary and Devil. If you find Trickster path deceiving before attacking Drezen, ask her to side with you as a mockery to the master during siege. You may set her free later.
