Sticky Gold

Name: Spider Sticky Gold
Rank: D
Element: No Element
Description: Through some reading he discovered the works of a Spider Cult in the Land of Rice Fields. He learned of their chakra-code for making a substance as hard as steel from a liquid they could use chakra to create. He figured he may as well try it out. Using his chakra and a little bit of saliva, he can infuse chakra into his saliva and swallow it, and force himself to regurgitate into his mouth with that infused chakra, a new substance, sticky gold. This substance is malleable like chewing gum, but within 3 seconds of leaving his mouth, it will harden into a substance like steel. Sadly, he is inefficient with this ability thus far and aside from a single special case, he can only create general projectiles, like boomerangs and arrows, he can make two at a time though.

Name: Spider War-Bow
Rank: C
Element: No Element
Description: This is the only special case thus far that Marco can create something bigger than an arrow with Spider Sticky Gold. He regurgitates the gold into the form of a large war bow, its tallness is a foot shorter than his height. This bow can fire arrows with extraordinary tension, and is as hard as steel. This does not count as a weapon more than a jutsu though, because it is chakra consuming to make, and it will only last him for an hour of heated combat. (About 10 Posts of heated combat, 15 of general hunting, 20 of training)

I believe that this is a KKG of one of the sound four.
