Rainbow Crystal Staff

The Rainbow Crystal Staff is a Hardmode, post-Plantera minion-summoning weapon that summons a temporary floating crystal which fires high-damage beams at enemies within its 60 tile range. The Rainbow Crystal is a sentry-style minion, similar to the Frost Hydra, only lasting one minute, remaining stationary, and not counting against the player's minion capacity. The Rainbow Crystal Staff has a 1/9 chance (11.11%) to be dropped by the Moon Lord.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stats bonuses, but these primarily affect the initial summon rather than the resulting minion. Minions cannot deal critical hits.
