This mod adds 4 new weapons and 1 new mob. More things will be out in the future. There is the katana, yari, kunai and musket. The one mob is the ninja villager which drops a strengthened iron ingot and uses kunai to fight. It is peaceful until you attack and will then start throwing kunai at you. The kunai are throwable and deal 5 damage each. The katana is a sword that deals 9 damage and the yari deals 10 but with a slower attack time. The musket requires musket balls to operate. There will be more in the future! Also, note that you may want to install JEI because all the recipes are kind of weird so I do recommend that.
