Silverwood fiber rope

Silverwood fiber rope is not especially strong or durable compared to other ropes and it is time consuming and difficult to manufacture.
Usually Silverwood fibers are interwoven with more mundane materials for added strength. As long at composite is roughly 50% made of Silverwood fibers, the rope can bind incorporeal creatures.
While extremely expensive, it is feasible to make an entire net out of Silverwood fiber.
Some magic spells that bind ghosts use a small symbolic loop of Silverwood fiber rope as an arcane focus.
