He has an attack of 100. Fir-Fir can have 2k+ HP after eating. If he doesn't have Annihilation, his armor absorbs 4/5 of the damage... You can take a 40% regeneration buff. And absorb as many attacks as you want. I think. If I didn't make any mistakes in my calculations. But does the dragon need to not have any affinities? Or not. Anyway, it's possible./
