Gensokyo/Nova Cannon

The Nova Cannon is a Hardmode, post-Moon Lord magic weapon. Its main fire mode shoots a ray of energy, capable of piercing enemies and applying the Daybroken debuff to them for additional damage. On contact with tiles, it causes an explosion similar to that created by the Inferno Fork. This explosion deals 40% less damage than the ray, but inflicts Daybroken for a longer duration.

The alternate fire mode spawns a small sun at the targeted location, which initially deals no damage. Over the course of 2.5 seconds, the sun will grow and turn deep red, finally destroying itself in a massive explosion that damages all enemies in a large radius. The base damage of the explosion is 2500; should the target survive, it also has the Daybroken debuff applied to it for a significant duration.

The alternate fire mode has a cooldown of 40 seconds and a base mana cost of 200.

Trivia

 * The base damage it deals is a reference to the number of the biblical Beast.
