How well would this Box?

I'm not surprised. Although the stats look great for boxing on paper, a lot of straight-up boxing is simply luck. Your best bet would be to max its melee stats, as well as prayer (if you're interested in ancient prayers). When I box I like to switch between attack and defense, but that doesn't seem to help any either. A bit frustrating, but that's how it goes.

 

Wow, let the money roll in already

 

Looks great for boxing, good luck!

 

If you switch attack styles at strategic times during the fight, I guarantee it will give you a significant advantage over your opponent, even when they have the exact same stats as you.

 

Pretty damn good I'd say.

If you were to level anything, master the HP. Get 99.
