Bow of Light

The Bow of Light is a unique Hardmode, post-Moon Lord true damage weapon that is rarely obtained from The Primordials's Treasure Bag. Holding the attack button will start charging an enemy-piercing light energy arrow, increasing its damage by 300 every half a second up to ten times, for a maximum damage of 3000. At full charge, the first enemy hit will unleash a light energy explosion, dealing two extra hits to nearby enemies.

Note that it has no specific class, as it deals true damage rather than melee, ranged, magic, summon, throwing, radiant, or symphonic damage. This also means that its damage value is not affected by any other damage modifications. It also cannot receive modifiers.

Trivia

 * The design of the weapon is a reference to a recurring bow of the same name in the  game series. It most closely resembles the Bow of Light from The Legend of Zelda: Breath of the Wild.
