Oncoming Maelstrom is the 1st stage of Wrath of Heaven. Next stage: Wrath of A-Cyclone.
Divine Cyclone has extremely high DPS and no knockbacks, so anti-Angel slow, freeze or knockback is mandatory rather than optional.
- Talented Sanzo Cat trivialises the stage; without the Talent, lean on Stilts Cat or the two Super Rares that target Angels.
- First-form ULTRA SOULS Ubers shine: Kasa Jizo, Issun Boshi and Ushiwakamaru kill the Cyclone faster, while The Grateful Crane, Princess Kaguya and Momotaro serve as powerful crowd-controllers.
Divine Cyclone's gimmick is being the first Cyclone to lack the Floating trait, requiring specialized anti-Angel units to counter it. Beyond that, it has all the typical attributes of a Cyclone: non-stop attacks and extreme health and DPS offset by pitiful range and somewhat low speed.
