Actually, you don't have to beat the challenger at all. At least, that's how the last plot was based. As long as you challenged the challenger (even if you lost) you got to move onto the next round. That is not to say that this plot is the same, however, but one would hope so.
I have found a leaf shield, two scarab rings, a greater healing potion, and fiery throwing marble (it's been in my trades forever) to be good for beating this guy. Oh, and the heal ability. That has been extremely helpful. My pet is 37 hp and I have beaten the Ravenous Monster 65 times (hp of 111). And, let's just say that I am not a fighter and have no freaking idea how I got that far. So, it must be the equipment and heal ability that I am using. Cause it's not due to my pet's hitpoints. She is a lover, not a fighter.
