I'm stuck on the challenge where you have to debuff the defense of the red dungeon master before getting to level 5. When I successfully made the debuff at lvl 4 it didn't count (I have been at level 6 or seven the time the challenges occured) )
In the description of a challenge, it is mentioned that the challenge has to be completed on Stage 5. You need to select a correct Stage, apply the debuff to a boss and complete the stage afterward.
I have completed level 5 with 3 defensive debuff being applied by 3 different champions and still did not complete challenge. Last one to complete dungeon challenge 2 please fix .
