Crown Jewel (enemy)
- For the accessory, see Crown Jewel
The Crown Jewel is an invincible boss servant that is summoned by King Slime in Revengeance Mode or during the Boss Rush at 50% health. The jewel hovers above the player and pursues them, firing red bolts. In Death Mode, the jewel is present for the entire fight. The servant will only despawn once King Slime is defeated.
