Game catchup: Puzzle Quest

(tags game, Dual Screen, hardware, puzzle)

I am only playing Puzzle Quest right now. I've been concentrating on beating the game, which means skipping optional stuff.

For a while there was one boss that was kicking me to the curb but I managed to clear it. Then from there it was smooth sailing. I think it's because I found a weapon that gives me extra damage because of my level and also I equip a ring that regenerates health. The enemies rarely regenerate health and they hit wimpy, so I am cleaning up.

Or I was until the final boss. That guy just owns me, with arbitrary spells and bonus. I ran away with my tail between my legs. I have no idea how I'm going to clear this guy, because frankly leveling up doesn't seem to do any thing.

There is part of the game that I am still unsure of, and that is the resistance points. How do I accumulate them and use them to my advantage?

I'm going to keep playing this game until I beat the end guy. It's proper.
