So I did the 2 challenges in the Diftwood Arena and realized after that I lost the Attar of the Blood Rose buff. It's pretty annoying since there is no warning about the risk of losing it so I'm not even sure it's intentional?
-If it's a bug, please fix it :P
-If it's not a bug, please warn the players that ALL buffs are removed when entering the arena. This way, it's possible to delay the arena to later (or just skip it) if we want to keep the buff longer
