My dragon, Daemonar, was killing a bunch of weaker straw blights in the island of the drowned, and I looted 1 Charged Blighted Bronze-sandstone Health Wing Scale. When I looked in my inventory, I had 251. Note: before going to island of the drowned and aquainting 1 of them, I had completely emptied my inventory to the pawn broker and my safe, or storage place. I checked my inventory before I went there.
Upon looting the corpse of the scale, I noticed I was not slow, but my inventory bar was full. I had a few other items I had aquired, about 20 to 30 or so, and the rest was the scale(s).
