Rainbow Crystal Staff

It is a magic weapon that has an 11.11% chance to be dropped by the Moon Lord. When used, the Rainbow Crystal Staff summons a floating crystal that the player cannot interact with but the crystal shoots beams of energy that deals significant damage to enemies within 60 blocks. The portal can not detect enemies through blocks but can detect enemies through platforms.
