Prosthesis Properties. This prosthesis can enhance or replace an arm, and has a built-in war fan that can be used to propel yourself with blasts of magical wind. It has the Blast (2d6 bludgeoning, 30 ft.) and Integrated (Tessen) properties.

Stick the Landing. When you fall, you can use your reaction to unleash a blast of wind moments before you hit the ground, cushioning you and reducing the falling damage you take to 0.

 “Eagles soar above
Where no man could ever reach
Good thing I’m no man.”
— Haiku written by Bombuku the Tanukin during the crafting of the first windweaver

Blast (XdX, X ft.). This prosthesis is capable of dis-charging powerful explosive blasts. The prosthesis is a martial ranged weapon with the Loading property. If you’re proficient with a martial ranged weapon, you’re considered proficient with this weapon. The information in parentheses notes the weapon’s damage dice, damage type, and range, respectively. This weapon doesn’t have a long range.

Alternatively, you can use an action to fire the cannon and propel yourself a distance up to the range of the blast in a straight line in any direction, dealing no damage. As normal, this movement can provoke opportunity attacks.

Integrated (X): The object in parentheses is integrated into the prosthesis, and can’t be separated from it, ex-changed for another integrated object, or used to make ranged attacks by throwing it. As a bonus action, you can extend or retract the integrated object, allowing it to be used or concealed, respectively. While an object is extended from an arm or hand prosthesis, you can manipulate it as if you were holding it, and your hand is not considered free. A prosthesis can only have one object integrated into it, which can be:

• A weapon without the Heavy property
• A shield
• A set of tools or handheld item that can conceivably fit within the prosthesis (GM’s discretion)
• An orb, rod, or wand
• A stash: a concealed storage space within the prosthesis, up to 35 inches cubed in volume, that can be used to store Tiny objects, such as rings, phials of liquid (e.g. potions), smoke bombs, pieces of ammunition, or a bag of caltrops or ball bearings. The user of the prosthesis can stow or retrieve an item from the stash as a bonus action. A creature can find this secret compartment with a successful DC 11 Intelligence (Investigation) check.
