Yeah the hydra is honestly the hardest boss to fight imo, cause stage 5 dragons do a whole lot of dmg but with dragon armor their breath doesn’t do much. And unless you have some way to deal with the poison from the hydra you’re kinda screwed cause you can’t out damage it with the poison 4 that you get
Hydra and dragons are unfair, because hydra is immortal until you set it on fire, and dragons have armor, so he can't deal enough damage, especially because as I seen, ice dragon has 500 hp and 61 armor point, so that's not fair
Literally the Hydra fight was a inmortal duel, if you don't have a attack like the Black hole from leviathan or Ignis stage 3 super sword attack, you can't kill Tremor, while, Hydra can't die until you set it on fire, and Tremorzilla can't
