This mod I have put together adds 3 swords, 6 throwables, 1 sticky, 3ish armor sets, 3 villager trading professions, and a structure. 2 of the swords in the game both do Divine Departure, and the other does a basic wind slash, and several of the kunai have unique powers. As well as Haki Knot and a merchant for them, or instead search for technique scrolls to learn grand power.
Note: I was not able to accomplish loot distribution to vanilla chests on the Fabric version.
