Blizzard has finally released the skill calculator, where you can plan the skill tree for your chosen class, be it the Barbarian, Demon Hunter, Monk, Witch Doctor, or Wizard. I'm going to follow my Asian stereotype and say that I'll probably choose the Monk with at least a Mantra of Healing and Transcendence for some uber healing ablities.
Through to level 30, you can choose up to six active skills as well as three passive skills. Additionally, each active skill can be enhanced with one of five runestones: Alabaster, Crimson, Golden, Indigo, and Obsidian. Some of their effects are better than others depending on the skill, but all of them are quite powerful nonetheless. I mean, the Crimson Runestone increases the rate of regeneration for Mantra of Healing to about 3 times the standard rate, while the Indigo Runestone forms a shield around you and your allies for 10 seconds. Not bad for a glowing rock.
What is your build of choice?
