Looks like Elan was right again.
it got limited by the 5 lb rule and so many times it was read that the object was to not weigh in total of 5 lb, and such, but I am guessing the bladder skin probably weighs more then 5 lbs.
The air bladder, as big s it is, would weigh more then 5 lbs, I figured.
But when combined with its contents, it is lighter than air - maybe a way to cheat the spell requirements?![]()
