We stayed 180 seconds in the pool from event start to end but we couldn’t clear it.
And pool debuff icon always be shown on HUD during event.
Are there any problems ? Or it need more detailed conditions?
I found out bug. During event, if battle wizard use ult, then battle wizard player’s debuff icon disappeared in short time. When battle wizard is using ult, she is in mid air status. This means battle wizard must not use ult for clearing challenge.
