This is the build I'll be rocking upon reaching level 30.
How to Use:
1- Start By Casting your Mantra to increase your attack speed (via rune) and reflect damage to those that attack in melee.
2- Next Breath of Heaven provides a hefty damage increase (via rune) even if the healing isn't needed. Recast as needed.
3- When you encounter an enemy Dashing Strike will get you there quickly, for relatively low cost and provide a dodge buff (via rune).
4- Once in melee range, Crippling Wave will be your first debuff +80% damage done to all affected (via rune) to apply to all enemies in front of you, cast this twice. (Don't use final attack, see below)
5- Exploding Palm will be the third attack in your flurry, applying a HEAVY bleed effect to up to 8 targets (via rune). If you're targets don't explode in a cascade of death AND step six is on cooldown, repeat steps 4 and 5.
6- Wave of Light will be your "Finisher" with the Obsidian rune the target will be dealt an enormous amount of damage and likely cause it to explode from the Palm Debuff, causing the aforementioned cascade of death.
