Immutable Form. The koboldzilla is immune to any spell or effect that would alter its form.

Kobold Apothesosis (Mythic Trait; Recharges after a Short or Long Rest). If the koboldzilla is reduced to 0 hit points, it doesn’t die or fall unconscious.

Its AC drops to 15, its Dexterity increase to 27 (+8), and its Intelligence and Wisdom increase to 16 (+3).
