Sorry you ran into issues! There is a bug where sometimes the player character is spawned in an incorrect position, it's supposed to drop you into the Arena area instead.
Okay I tried a few times with a few different characters. while the debuffs work. It continues to spawn me in the same room with the mage class even if I choose otherwise.
Thanks for taking the time to check it out again. Sadly we didn't have time to implement combat for each class, they just affect your stats (damage, attack speed, movement speed, health).
