I have noticed in endless archive when we take the side routes and get turned into a goat or a watcher we loose our weapon and jewelry 5th piece bonus. What I mean by this is I run drakes rush on my tank weapons and jewelry. After I have been transformed transform back enter the next area my drakes rush does not work. I then have to take at least one piece off and put it back on. Im not sure if this is an issue on any other set I have noticed this issue at least with drakes it may be happening to other buff sets or proc sets.
