I got the pagoda gauntlet bundle and have been playing it with some friends. I noticed that my exp. kept going down and is now at zero. Why did it do this and will I get to keep battling it for experience?
All dungeons, in the game and gauntlets give quest XP twice only. First time through you get full XP, second time through half XP. Every run after that is just battle XP and gear drops with 0 quest XP.
It is because you do it once for full experience and then a second time for half and then third time the charm! zero experience Miranda Dreamsong Brandon Dreamsong- watch for my brother
