The chest

the chest contained an array of things, Two folding swords made of lightweight steel, a metal re curve bow enchanted with silence and speed faster than light. A mask shaped into a skull a tomahawk with the words "Revenge is the only answer" engraved into it, these were all inside the chest.

The Hidden blades are infused with a special chakra spell, The right one has fire aspect setting the target on fire within contact, the other Ice aspect freezing the body part of contact the blade has made with. The tomahawk has kinetic energy channeling stealing the opponents energy turning it into it's own for maximum damage.

A knew blade was forged while obtaining Darkryi a chain is now on his hidden blade the one with kinetic energy absorption making it deadlier.
