The Rainbow Crystal Staff is a Hardmode, post-Moon Lord sentry summon weapon. It can summon the Rainbow Crystal sentry, which lasts for 10 minutes, remains stationary, and does not count against the player's minion capacity. The Rainbow Crystal attacks enemies within its 62.5-tile range by firing spreads of three multicolored rays of light, which prioritize targeting the nearest enemy. Each of these beams then releases a twinkling star that produces a damaging explosion after a short delay. Unlike other sentry summons, the Rainbow Crystal floats in midair at the cursor position when summoned, rather than falling to the ground, similarly to the Lunar Portal Staff. The Rainbow Crystal Staff has a 2/9 (22.22%) chance of being dropped by the Moon Lord.
Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Rainbow Crystal Staff has over a Ruthless one is knockback.
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 ⚷ Open / Activate 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
- This weapon has a 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.
Trivia
- Unlike most other rainbow-themed weapons, the Rainbow Crystal Staff does not have secret color themes for developers or beta testers.
- 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.
- 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.
