Super Plasma Cannon

The Super Plasma Cannon is a Hardmode magic weapon that drops from Martian Saucers during the Martian Madness event. It launches a ball of energized plasma that explodes on contact after piercing through 2 enemies or on tile collision, releasing 16 smaller plasma projectiles in all directions that pierce infinitely and deal decreased damage. Holding the attack button and then releasing after one second will unleash an empowered version that explodes into 4 normal versions.

Its best Modifier is Mythical.
