If you ever add things in about the knight training grounds, put in that you ARE able to take food in. I beat all the knights with a couple restore pots and an inventory of food. \ I was using tuna though (it's what I had at the time), so using sharks probably makes it even easier. : and NO, you do not lose anything when you die in the waves, but for some reason, when I beat the waves, I came out with the amount of hit points and reduced stats that I had when I won...wierd. :shock:
