How to make OP character, vol 1.
Unlock brewer. It shouldn't be hard.
Invest all your money in his first ability, and if you maxed it, invest gold in one level of fourth ability and second ability.
Pick up every spell. Save only power ups, first attacks, and, if you want, fireballs. Trade everything else. This way you will get MANY HP and lots of attack power (20% of getting one from trading it for health). Like this comment for others to see!

Hey TuxPL! I'd really like to make it for Windows Phone too. I'll be looking into that in the New Year :) Thanks for the question and for making 10s!
