ACTRESS CAT B Hits multiple enemies at once for budget crowd damage. Mesocosmocyclone hits at 5-frame attack rate (extreme DPS) and Warps FORWARD. Crowd-control with Seafarer Cat or Corrupted Psychocat; ELEMENTAL PIXIES Ubers are ideal.
Mesocosmocyclone boss with Super Cosmic Cyclone backup. The Cyclones push hard and Warp FORWARD (not back) at extreme attack speed — frontline goes from full to gone in three seconds without Warp Immune. Community fix: Manic Mohawk warp-immune meatshields + A. Bahamut (Explosion talent if possible) for knockback chaining + Bombercat or Lumina as the Anti-Alien tank. Common failure: assuming Warp Immune is optional. The Cyclones will warp your backline DPS out of attack range otherwise. Some players consider this the second-hardest Mystery Mask stage after 3-45 N77.
