BOSS
PRIMEVAL CYCLONE
Extinction's Vortex is the 3rd stage of Typhoon Nemo. Previous stage: Creation's Gyre.
STRATEGY
Balanced around Cats of the Cosmos Chapter 3: the Starred Aliens carry huge strength magnifications, and the Angel backliners outlast the Cyclone — max your Anti-Starred Alien Treasures first.
- Focus the backliners before the Cyclone: Long Distance units (Fiend Cat, Golfer Cat, Awakened Mina) and Wave attackers (Manic Macho Legs, Talented Pizza Cat), with a Talented Rodeo Cat keeping the Cyclone off the LD stack.
- A sample lineup from the wiki: 3 meatshields, Rodeo Cat and 6 LD/Wave units; swap a couple for long-range attackers in case the Cyclone dies before the backline does.
- If the Cyclone itself is the problem, kill it first with Slapstick Cats — at level 50 they survive an extra Corporal Weyland hit, and their Talent adds a Weaken.
- After the Cyclone it is attrition: whittle the Angels with midrangers while Ramen and Cyberpunk hold or regain ground.

Primeval Cyclone BOSS
Compared to other Cyclones, Primeval Cyclone moves very fast at 18 speed and curses everything it hits. However, it has a relatively low damage output (7,777), which allows it to be stopped via weaken.
