I transformed a pvp chest into the set piece but now i realize i want to leave the chest as a pvp piece.
can i put it back into the catalyst and reverse the process?
Nope. You now have a set bonus item.
If you’re worried about losing out on Versatility for whatever reason, a lot of folks are giving up some of the Vers (since you lost the bonuses to Vers on trinkets) in favor of 2/4 piece.
Best defense is a good offense. Zug harder >:0.
