Last Prism



The Last Prism is a Hardmode, post-Moon Lord magic weapon that fires several beams of light that converge into one as it charges. It deals a massive amount of damage, but also consumes mana very quickly. The Last Prism has a 1/9 chance (11.11%) of being dropped by the Moon Lord.

The Last Prism projects 6 beams that deal individual damage as they begin to rotate out of the prism's tip, then spin faster as they converge into one thick beam. This process takes approximately 4 seconds, each beam continuing to deal the weapon's full listed damage. The fully-converged beam therefore deals 6 times the listed damage, for an output of 600 damage per hit. Like all piercing attacks, the weapon hits once every 0.1667 seconds or 10 game ticks. The mana cost will increase massively as the beam converges.

However, due to the high mana cost (12 mana 6 times per second when fully charged = 72 mana per second), players will struggle to maintain the beam for more than 5-6 seconds. A Mana Flower, Magic Cuffs, Nebula armor, and a large supply of Super Mana Potions may be required for continuous use.

The Last Prism cannot deal any knockback.

Its best Modifier is Demonic or Mystic.

Tips

 * Although Super Mana Potions are the only effective way to continuously shoot the beam, they do heavily reduce your damage with the Mana Sickness debuff. Mana Flower is the best way to achieve this as if you miss your timing on drinking a potion the beam will break and need to be restarted. Using the Celestial Cuffs can substantially reduce your mana usage in some situations, allowing for much higher sustained damage.
 * 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. This dispersal makes little difference against large bosses and/or groups of enemies, however, making the Last Prism ideal for such situations if you aren't using the Mana Flower to fire continuously.
 * When using Last Prism in combination with Nebula Armor and the UFO mount the Moon Lord fight becomes significantly easier. The buffs created by the Nebula armor create high damage output and constant health and mana regeneration which makes mana potions unnecessary, and significantly reduces the need for healing potions. One can constantly circle the boss and easily collect the buffs while avoiding attacks with the Cosmic Car Key. In this way Moon Lord can be killed in 4 minutes even on Expert mode using this weapon.

Trivia

 * The Last Prism beam has the same sound effect as the Phaseblade/Phasesaber
 * Upon activating the weapon, it produces the sound of a Jetpack/Aqua Scepter for a short time.
 * The beam changes to various different colors if the character's name is one of the following: Tsuki, Yoraiz0r, Ghostar, Devalaous, Leinfors, Aeroblop, Doylee, Darkhalis, Arkhalis, Nike Leon, Suweeka, W1K, and Grox The Great, which are the names of various testers for Terraria. The name "Random" also seems to have an effect.
 * The Last Prism has approximately 11k burst DPS against a single target, whereas the S.D.M.G. has only approximately 8k dps in the best case, making the Last Prism the highest damage weapon in the game short-term. Over a long period, the S.D.M.G and Last Prism both average about 7-8k with all possible buffs and best possible gear+modifier. However, the Prism pulls ahead when used against hordes of enemies, or while moving.
