Revenge of R-Cyclone is the 3rd stage of Crimson Catastrophe. Previous stage: Wrath of R-Cyclone.
Red Cyclone has a single knockback and pushes at insane speed unless frozen or slowed, while Mr. Mole hides behind it and wrecks your stack with rapid Long Distance knockback (350–900).
- Mr. Mole attacks every 4 seconds, so skip anything slower than speed 5, anything with a foreswing near 4 seconds, or anything under 9,000 HP.
- Levelled crowd-control units — Sanzo, Witch Cat, Necromancer, iCat — reach the Cyclone; even Dragon Cat plus CC gets there eventually.
- Courier Cat and Awakened Bahamut have short foreswings and survive Mr. Mole repeatedly; once the Cyclone is slowed or frozen, Awakened Bahamut kills it almost instantly.
- Stall at the start for wallet, stack 3–4 CC units, then stream CC and attackers; slow or freeze the Cyclone the moment it spawns.
Red horned peon — 15,000 HP, 500 AP area attack at 40 melee range. Tanky for a peon. Anti-Red Ubers (Mighty Reza, Crazed Bahamut) clear easily.
Red Cyclone deals absurd damage and attacks non-stop, destroying anything it touches in less than a second. However, it has one of the shortest ranges in the game, somewhat slow speed, and two exploitable traits.
