RUNS The Great Diablo & The Greatest Diablo — every Friday, all day SEE THE SCHEDULE →
The 11th Cyclone Stage, added in Version 10.8 and running every Friday. Wrath of Hell introduces the Aku Cyclone and gives a 30% chance at Aku Researcher; The Greatest Diablo (Version 12.4) adds two stages — 1,000,000 XP, then Aku Researcher's True Form, Cat Researcher. Its first stage shares the name Wrath of Hell, at Merciless with a rarity restriction.
Aku Cyclone is an Aku Cyclone with 1,666,666 HP, 6,666 area damage at 200 range every 6 frames, speed 3, four knockbacks and an Aku Shield of 1,666,666 that regenerates to full — the Shield blocks status effects, so it is Shield Piercers or brute force. The wiki notes its damage and health are built from the Number of the Beast, and it is the only Cyclone that guarantees a full wallet refill when it dies.
