Did I get this accurately?
As far as I know, there has never been an event in Sprite, LOD, Void/Cult, CDepths, and WLab after the release of the new waki.
Furthermore, the Battle Nexus and Mad God Mayhem have never seen a chest or other event (beyond just keys dropping) and thus they don’t really count.
EDIT: Was there ever an event where Frost CWand dropped at an increased rate due to a chest event?
EDIT 2: This is gonna give DECA ideas isn’t it…
