Kunais and Shurikens are one of the most essential parts of the gameplay. Theyre a consistent way for damage to be done to an individual that you are in combat with. Kunai and Shuriken come in three different bindable “Jutsu” (the server term for a move that can be bound to an item): Throwing Kunai, Throwing Shuriken and Multi Kunais.
For Throwing Kunai and Throwing Shuriken they both work in the exact same manner. Costing 1 arrow or flint (Flint - Shuriken & Arrow - Kunai) to throw a single arrow forward at high velocity. The nature of this arrow is projectile so when aiming this you should be considering the location your opponent will be rather than where they are in the moment of firing. Each arrow that you hit deals a solid 1.5 hearts of damage and you can rapidly throw a Kunai then a shuriken. These two jutsu have an extremely low cooldown of around 2 seconds each.
Multi Kunais however work as more of an area coverage. Costing 5 arrows to fire this will send a volley. One arrow dealing 1.5 (the maximum this jutsu can deal) this is less aim oriented and requires less actual ability to hit however costs more and has a longer cooldown to use requiring a wait time of 15 seconds to use again.
