Title says the description. I got some of these names from google searching. Since I saw a construction site beside Tachi base. I'm assuming it's Ninja Town.
Throwing Stars/Kunai
Basic throwing weapon. No freeze rate. 5 damage. Somewhat average rate of fire.
Smoke Bomb
Toss a smoke bomb at your feet which grants you invisibility for 4 seconds. Getting damaged will cancel the effect.
Rolling technique
Leap forward with a burst of speed and roll granting invulnerability during the rolling animation. Useful for avoiding spammers or escaping tight situations.
Nunchucks
Very fast melee weapon. (needs special attack/ability)
Wooden Bo-Staff
Similar to Bamboo rod but with a slightly different ability. Spin attack has less freeze rate but doesn't reflect back bullets. Lowers damage taken during spin animation.
Neko-te (Claws)
Grants 3% movement speed boost. Very fast melee weapon.
Kusari (Chain based weapon)
Deals 4 damage but has wide range and fast melee rate.
Torinoko (Flash bomb)
Toss a small explosive bomb to blind enemies that are within blast radius of the explosive. Does no damage. Blinding lasts 4 seconds.
Sprinting
Increases movement speed by 15% with the cost of taking extra damage and cannot use weapons during sprinting. If used too long, your character will tire out and will be frozen for 5 seconds to catch his/her breath. Taking out a weapon will automatically cancel the sprint. Use sprint again during sprint animation to cancel the sprint effect.
Crossbow/Improved bow (needed a ranged ninja weapon somehow)
Launches an arrow in an arc. Does 7 damage. 1 clip. Good reload freeze. No freeze rate. Bad rate of fire.
Feel free to add more suggestions to this list or suggest balance improvements on these weapons/items.
