Cursed Flames

The Cursed Flames is a magic weapon from 1.1 update. It has a Fire Flower style of attack, but fires are green colored.

It can be held down to shoot repeatedly.

The fireballs seem to move at a higher velocity than those from the Fire Flower.

It is also worth noting, the projectiles can travel in water and even set enemies on fire underwater. Something no other fire based spell can achieve.
