A think blue rope with powers of self adhesion
Can support up to 1000lbs without breaking, and adhesive/sticking properties support the same.
Costs 100cr per foot
Disolution Formulae costs 25cr per use (weights 0.1lb)
This blue rope is supremely strong and can carry up to 1000lbs, but more than that, if the cut end is pushed against an inanimate object it will stick fast and still support that weight without the need to tie it off.
The rope can be cut to provide a new sticky end (a foot of rope must be removed) or a formulae applied that dissolves the substance and allows the rope to be reused.
