Phantasm

The Phantasm is a Hardmode, post-Lunatic Cultist craftable bow that auto-fires four arrows at once, while only consuming a single arrow from the player's inventory. Arrows are loosely grouped and can fire with varied velocities and ranges (similar to the Chlorophyte Shotbow). The bow has a 66% chance of not consuming ammunition.

Constantly shooting with the Phantasm will gradually increase its firerate, up to a cap. Stopping the attack or switching to another item will reset this effect immediately, making switching weapons inefficient.

In addition, each successful hit on an enemy causes an additional barrage of magical arrow projectiles to fire and home in on the target that was hit initially, with no additional ammo or mana cost. The rate of fire of these projectiles depends on the current rate of fire of the Phantasm.

Tips

 * If used against the Celestial Pillar during the Lunar Event, the bow can destroy a single Tower within a few seconds due to its extremely high damage output. Combined with its high velocity, a pillar can easily be shot at from a distance.
 * Try not to use piercing arrows, as enemies will have a brief period of invulnerability and many arrows will pass through without causing damage.
 * Using Ichor Arrows reduces the defense of enemies you hit, increasing the damage from the extra shots as well as the extra barrage, increasing damage output significantly.
 * The Phantasm is a good choice for the Dungeon Guardian as it has one of the highest projectiles fired per second.
 * Even though it has a high chance not to consume ammo, it may prove useful to use the Endless Quiver.

Trivia

 * The Phantasm is the only celestial weapon that doesn't have a tagline.
 * The Phantasm is the only arrow-consuming weapon in the game that has a chance to not consume ammo.
