Crystal Slime

The Crystal Slime is a minion frequently summoned by the Queen Slime. It poses a minimal threat to the player and is designed to distract you during the fight, however in Master mode, it poses a much greater threat and significantly increases the difficulty of the boss fight as its projectile attack will now inflict significantly more damage and will also cover a far larger area. Although it is meant to be a distraction you should deal with them and keep attacking them.

Crystal Slimes stop spawning once the Queen Slime transfers to her second phase.
