Did anyone figure out if it was -10 BP timer PAST 45 limit? It is the deciding factor between "Not worth it" and "Must have".
No, the staffs do not take you past the 45 cap. I went ahead and upgraded mine anyway. Mainly because snow and breeze geodes are easy to come by and I figured that I will probably want to upgrade them for the next trial so I might as well do it now. For now, however, the +2 makes no difference at all if you already have -15 BP timer in your current gear.
