  • 4♛ difficulty for this sub-chapter makes no change to enemy strength magnifications and only allows Special Cats and Rare Cats to be deployed.

New Features

This sub-chapter introduces one new enemy:

  • Othom: Mooth's Relic/Floating variant, with high health, damage and speed, plus a 100% chance to Curse cats for 2 seconds. Notably, he attacks from a range of 340 but hits cats up to 440px away, allowing it to outrange many more units.
