Embersilk

Embersilk is found in the Gnarled Oak forest. It's a product of the forest overgrown spiders' exposure to the "wild dust" of the area. Due to it's unnatural tensile strength, it has countless applications and potential uses. If the silk is coated in shadowfin blood and is allowed to dry, it hardens to the shape it dries in, tripling the stength of the threads.
