Spirit Cannon
Spirit Cannons are large mounted guns designed to receive an input of Energy from their user, enhancing it and firing it off as a powerful energy projectile. Spirit Cannons have the capacity to shoot up to 3 miles way, taking a single Energy charge from their user and converting it into an Energy projectile that causes 1d20 + [User's Potency] Damage. The Energy projectile itself typically behaves as an unmodified Damaging Projectile Technique, but some models might be designed to enhance the energy in such a way as if it were Modified with Homing, Powerful Knockback, and other common modifications for energy projectiles.
Spirit Cannons don't share a particular aesthetic amongst each of the different models; each manufacturer produces it in their own way in accordance to the features it will have as well as exactly where it will be mounted. What they do share is the same type of Energy conversion Technology, which serves to transform ki into a powerful damaging blast.
