After defeating Plantera and Golem, you make your to the underground mushroom biome to farm for some truffle worms to farm Duke Fishron for the razorblade typhoon

Once you geared up, you make your way to the dungeon where you brutally destroyed the other cultists, when you finished with the last one

You heard a noise behind you and saw the lunatic cultist absorb part of the power of the table. However, this lunatic cultist was female

The lunatic cultist stands up menacingly and tells you in a crazy and threatening voice

Lunatic Cultist: Get ready for real hell!
