Unstoppable

Unstoppable is earned by completing the Boneyard with a Monk cat. This unlocks the Unstoppable passive ability, which makes your cat immune to knockback, Stun, Slow, and other mobility debuffs. The upgraded version expands this to full debuff immunity. This is a foundational Monk passive that removes many of the most dangerous crowd control effects in the game. It also enables powerful synergies: Meditate's sleep drawback is negated since sleep counts as a mobility debuff, letting you gain its full healing and stat bonuses risk-free. Upgraded Invert also loses its downside, allowing repeated stat manipulation without penalty.
