When you are attacking your opponent with a godsword, your opponent can eat 2 pieces of food between your 2 hits. Thanks of the saradomin brew, you can eat 2 pieces of food + drinking 1 sara brew which restores in total 63 hp. That's way too much and it fucks up pking, because every time you want to use your special attack with a godsword when using by example a whip, he can eat 1 piece of food + drinking 1 sara brew which restores 40 hp...
I don't know if it's made so, but I think it can't be the meaning of that. You have to set a timer between eating a piece of food and drinking a potion, because there isn't one now and their should be one, because potions can heal also like food ( and their is a timer between eating food ).
