Last Prism

The Last Prism is a Magic weapon that has a 11.11% of dropping from the Moon Lord.

Often considered the most powerful obtainable weapon, it deals a massive amount of damage, but also consumes mana incredibly quickly. When used, the prism emits six beams of light that deal individual damage and rotate in a conical pattern emanating from the prism's tip. As the prism fires, the beams grow closer together, spinning faster as the beam charges. After approximately 4 seconds, the beams will appear to merge into one larger beam, each continuing to deal the full listed damage of the weapon, thus dealing six times the listed damage per 9 ticks (0.15 seconds). This means without crits or damage amplification this weapon does 600 damage per hit when fully charged, hitting 6.66 times per second, which gives 4000 base DPS with all six beams connecting (easier when all beams merge into one). The same amount of damage can be dealt when the beam is not fully charged, but the damage will be dispersed over a large area, making many beams miss at any given moment. This dispersal makes little difference against large bosses and/or groups of enemies, however, making the Last Prism ideal for such situations. However, due to the high mana cost (12 mana 6 times per second when fully charged is 72 mana per second) players will struggle to maintain the beam for more than 5-6 seconds. A Mana Flower, Nebula armor and a healthy supply of Super Mana Potions are all recommended for continuous use of this weapon. Although Super Mana Potions are the only effective way to continuously shoot the beam, they do substantially reduce your damage with the mana potion debuff. Using the Celestial Cuffs can substantially reduce your mana usage in some situations, allowing for much higher sustained damage. The beam does not pass through blocks but can pass through platforms.

Because the weapon has no knockback, it is unable to acquire the Mythical modifier. Therefore, the best modifier is Demonic or Mystic.
