Description:
The Bone Crawler is a new spider like mob that will rarely spawn naturally in the Betweenlands. It has 3 sizes and 1 mini-boss version. The three sizes determine it's strength, damage, and health. This mob would shoot out a large web like net at you. Rapping you up on contact causing decay for 2 seconds. Only Large bone crawlers, and the Bone Crawler Patriarch mini-boss can. The large and mini-boss wear slimy bone armor to protect them. You must hit these armor pieces knocking them off allowing you to damage them. The Bone Crawler Patriarch has 1 Matriarch Chiromaw wing on it's abdomen which can shoot 5 Chiromaw barbs at you in a small explosion towards it's enemy. Also these spiders can swiftly move up walls and ceilings able to jump at you.

(A side note: Chiromaw's and Bone Crawlers hate eachother)
