First point at level 30 goes in Triple Swing.
Level 31, 2 more points in Triple Swing. You get Mastery at that level and it requires 3 Triple Swing. Start pumping Mastery from there.
After you max Mastery, you'll have a couple of points. Use them however you want.
At level 39 start saving points. At level 45 you get Combo Smash. It maxes at 20 points, you should be able to max it right away.
From there on find out what skills you get when and use your points whatever way you want.
That's pretty much the cookiecutter build :rolleyes:
