Phantasm

Phantasm can be crafted after defeating the vortex pillar, it does not require you to have defeated the moon boss as it does not require any luminite bars.

The bow fire 4 arrows at once giving it a huge DPS. In addition, when focusing 1 opponent the bow fires a continuous stream of arrows in between its attacks, rewarding players that land multiple attacks in a row. This is easily the highest DPS bow; when used correctly with the right set up you can get well over 4,000 DPS on a single target.

It is recommended to craft this bow to fight the moon boss that appears after defeating all the celestial pillars.

However, this bow's downside is that if there are multiple mobs that have few hit points (killable in 2 volleys or fewer) as you are unable to use its passive to its full potential and you are better off using the other celestial pillar weapons with area of effect attacks, such as the vortex beater.
