Battle Cats Wiki

Ominous Fin Alert is the third stage in Cats of a Common Sea.


  • Infinite Trolly Bloggers spawn after 6.67 seconds200f, delay 10~13.33 seconds300f~400f.
  • 3 Devil Wives spawn after 13.33 seconds400f, delay 16.67~23.33 seconds500f~700f.
  • 1 H. Nah spawns after 26.67 seconds800f.
  • When the base reaches 99% HP:


H. Nahs themselves don't sound all that difficult and neither are the Cala Marias, but the presence of Devil Wives can wipe their usual counters in no time flat. For this reason, it's recommended to have means of hitting Cala Maria behind enemy lines and bring Surge-Immune units. Your attackers should ideally outrange H. Nah, or else his damage and knockback ability will effectively stun-lock them, rendering them all useless.

Recommended Units[]

  • Stone Cat: With the extreme quantity of DPS on the frontline, most meatshields won't be able to survive long enough. Stone's extreme health and Surge/Knockback Immunity however dismisses all of these concerns. Stone cannot serve as your only means of defense due to despawning soon afterwards, but it does significantly reduces pressure for other units, especially when boosted by research combos.

Recommended Ubers[]

  • Kasli the Bane: Kasli the Bane is Surge Immune and her own Surges can disable H. Nah's knockback while easily removing Devil Wives, and may even snipe Cala Maria. Kasli also outranges everything save for Cala Maria, making her a safe pick as long as a Surge-Immune frontline is there to prevent H. Nahs from damaging her.
  • Divine Lilin π: Divine Lilin π can (barely) outrange H. nah, which will increase as she can use the other peons to snipe as well as to help her reposition, while also utilizing her surge to clear them away. Additionally, the only other traits besides Traitless are Aku and Angel, which she is strong against.
