Rainbow Crystal Staff

The Rainbow Crystal Staff is a Hardmode, post-Moon Lord sentry summon weapon. The Rainbow Crystal Staff has a chance to be dropped by the Moon Lord.
The Rainbow Crystal Staff summons a temporary crystal that deals high damage to enemies within its 60-tile range. Unlike other sentry summons, the crystal floats in midair at the cursor position when summoned, rather than falling to the ground. Attacks are animated as a spread of colored light beams targeting the closest enemy. The beams themselves do not do damage; damage is dealt only by delayed explosions at the end of the beams.
== Notes ==
* The crystal may sporadically attack through blocks, though this does not occur often.
* The light beams from the crystal will detect enemies that have not appeared on-screen yet. This is useful for detecting which direction new enemies will appear from.
* Pressing while aiming at an enemy will focus fire on that enemy until killed or the target has been switched.
* As with all sentry summons, summoning another sentry will cause the crystal to disappear unless the player has an accessory to increase the limit.
== Tips ==
* Though it has the highest base damage of any summoning weapon in the game, the long delay before the Rainbow Crystal creates a damaging hitbox makes it almost completely useless against fast enemies. It is effective only if the player can somehow lure enemies into getting stuck in one place or force it to target areas where enemies are guaranteed to appear (such as right next to the Mysterious Portals in the Old One's Army). If the player is being chased by an enemy, it is possible (and very likely) that the Rainbow Crystal will be unable to land a single hit on the pursuer.
** The Stardust Guardian can draw the aggro of a handful of grounded-based enemies and lure them to a single spot where the Rainbow Crystal can pick them off.
* This weapon has massive range and can target enemies far off-screen, though it prefers to aim at closer targets. As such, it is recommended to place this sentry high in the air to provide it with the widest view; its accuracy will not improve if it is close to its target.
* Because it does an immense amount of damage upon contact with players in PvP and can be placed in midair, most regulated PvP servers ban the use of this weapon.
== Trivia ==
* The quote in its tooltip, "The colors, Duke, the colors!", is a reference to a popsicle commercial.
* The Rainbow Crystal Staff has the highest base damage of all sentry summon weapons.
* When summoned through mods or 3rd-party software, its projectile’s color is red.
