NO! I mean I put all the potions in my boxes, and carry with me 6 items to the boss fight. When I run out of health (or mana), I just Invisibility and then move my boxes then exchange the items, then continue the fight. But now I can't use that technique any more, since every time I use "move boxes" ability, my Invisibility break. I could bring the boxes before I used Invisibility, but it really bad because I use my Invisibility in emergence case...
