I don’t really know what quite caused this, just that it happened, but I’ll try to explain as best as I can.
As an ele, I changed to dagger/dagger during Simin, Dwayna priestess to get the most DPS possible. After a really lengthy battle, we managed to kill her. After fighting her, I tried to switch back to Staff, but couldn’t.
I wasn’t getting the message that I was still in combat, and every time I double clicked my staff, I heard the equip audio cue, but the staff refused to equip and I was still in dagger/dagger.
Logging back out, and then back in fixed this eventually, so it’s not a serious bug, but it was a bit odd that I had to leave the dungeon to get my staff equipped.
