Uhh your manners?
And probably RPG basics. Try equipping better gear and using the elemental weaknesses. If youre in the Seal of Flesh before making it to the hub town, then you're probably too early. If you're still having trouble, just get fat. It's kinda the gimmick of the game. Ass Quake and Belly Slam destroy most thing and the fattening healing items are better than anything else.
