“We have decided not to announce the challenges before the league starts, so that the team have freedom to keep adjusting the challenges as final testing continues,” explains the studio. “This league’s challenges follow a similar format to the ones you’re familiar with, so there should be no unexpected surprises there.”
GGG has also piped up on the balance fixes coming in the update; of note, mods that debuff monster damage will “now actually work properly,” key farming mobs (like Oni-Goroshi) won’t pop as often and will kick your butt when he does, normal mobs will drop fewer items, and sextant spam/blocking/abuse should no longer be a factor in league play.
Patch notes are up now; the trailers are below!
