The Empress is a boss from the latest global update, showcased together with the Queen Slime. After a victory over Plantera, you will notice a little rainbow fairy in the dusk Hallow. Squish it, and her big sister will come after you in a short while.
The power of the sun makes her inadequately strong so that a single punch will drop you dead no matter what an enchanted helmet you wear. The evening gives you an advantage, but you still need a firm shell to survive at least a few of the empress’s attacks. It’s an optional boss, but honestly, there is no place for glitter in the war game!
