What Hydra does
Reported values conflict: guides list either a 5x or 8x earnings boost, while mutation-upgrade reports range from 15% to 40% every 10 minutes.
Hydra is classified as a Mutation upgrade pet. You can deploy one pet per farm floor, so the practical question is whether this role beats what you already have equipped rather than whether the pet is good in isolation.
How to get Hydra
Hydra hatches from the Secret Egg at a 52% chance. The egg costs $7.5Qn from the Egg Merchant. Hatching is pure chance with no pity system, so budget for multiple attempts at low hatch rates.
