Hey, I am a little bit annoyed by moving stuff around on between different characters. The easy solution is to put stuff in shared inventory slots. The big question is: How many should you get?
Currently I have four slots filled with three infinte salvage kits and a lounge pass. I can think of other items like the Birthday Cake, Position Rewinder or the White Mantle Portal Device.
I am curious what you keep in your shared slots.
That one empty one is from SotO and so far I use it for Runestones when switching through my alts, so it automatically adds up there and can be sold as a stack at the end.
