Ravager Twine

Ravager Twine is a new block/item, which is dropped when a Ravager is killed and can be found in loot chests of mansions & outposts. It looks like grayish brown string, and can be placed in the world like string, and can be part of tripwire circuits. Unlike string, it is not washed away by water, and can be waterlogged. Also, villagers don't pathfind through it, and treat it as an opaque solid block. Four Ravager Twine can be crafted into/from Ill Wool. Ill Wool can be brewed with an awkward potion to make an ominous bottle I. Six Ill Wool and a stick can be crafted into a blank "ill banner" which can have 7 patterns applied.
