I have an idea for KATROCC Lunar Stones: i have a great idea for KATROCC, and it's Lunar Stones! You can only get Lunar Stones on EX stages after defeating the DX corrupted boss. Lunar Stones unlock more EX stages. after beating level five of the game and getting five Sun Stones, a level 1 EX stage will appear, and it will be harder. Then, once you come across enemies, you'll see they are fully corrupted and chasing you. And when you get to the boss of the stage, (or miniboss) you'll see they have been fully corrupted as well as being a DX boss! On the half health phase, they'll get so mad, that they get SUPER CHARGED WITH CORRUPTION! If you manage to beat the DX Fully-corrupted boss, you'll get the Lunar Stone! Getting ALL the Lunar Stones, you'll be able to face Corruption Curse, but.... He's the Soul Version and VERY HARD!
