If you want to beat the Hydra in Sonny 2, (Found in the tunnel of illusions), you will need the move known as Envenom, you will also need some weapoons with high fire piercing. You need to poison both of the Fire Claws, and then you need to take down The Hydra with you fire weapons (after poisoning the Fire Clas to death), posioning is really effective against Fire Claws, use it. Thanks,
Actually, while a venom bio is good against the Fire claws, a strength or speed based bio is good against the Hydra itself. The Hydra is resistant against venom, likewise the Fire Claws are resistant against physical attacks.
kill the easiers ones with the speed build(toicant form, shadow blend, agile expousure, withdrawl) then the best.If you want, use crystalize in one of them.
