Kharazim is a great hero. Having a strong AoE heal, many ways to increase you and your allies' speed and the ability to deal out damage and easily finish fleeing heroes makes him not just a reliable support, but a deadly one.

The basics of this build involve around three talents, ( Insight, Blazing Fists and Fists of Fury) and Kharazim's basic attacks and ability, Deadly Reach. If done correctly, a Kharazim player can go through the entire duration of Deadly Reach, only to have the cooldown having already reset and another Deadly Reach be ready, and so the loop continues. Additionally, mana won't be much of an issue due to the mana topup from Insight.

There's not much else to say here, so read on below to see how the build works and what talents you should pick.

Level 1: - Insight is the first core mechanic of this build and a very powerful talent. Having a top up of mana every third basic attack (which includes Radiant Dash and Deadly Reach basic attacks) and his reasonably fast basic attack speed means that you won't be struggling for mana very much, which also means less time leaving the battle to regen your mana at the healing fountain or spawn. Ideally, you want to complete the quest (Obtain 100 stacks of insight, 1 stack is gained per every third basic attack) as soon as you can.

Level 4: The level 4 talent is entirely up to your preferred choice and what your team needs. If you find your team requiring extra healing, go for Spirit Ally, if you find your team taking a lot of basic attack damage, go for Earth Ally and if you have a lot of enemy heroes relying on stealth (Such as Nova and Zeratul, go for Air Ally.

Level 7: - Blazing Fists is the second core mechanic of this build. The cooldown reduction from this talent stacks with the cooldown reduction from Insight, meaning that with the completed quest from Insight, every third attack will reduce the cooldown of Deadly Reach by 1.75 seconds.

Level 10: Although I personally recommend Divine Palm, the choice here is both situational depending on your allies and enemies, and up to you. If you find yourself (Or an ally) getting damaged or killed too quickly, then Divine Palm should be the heroic to choose. If you want a way to deal with a bunch of grouped up heroes more effectively or to maximize your damage, go for Seven-Sided Strike.

Level 13: - Fists of Fury is the third and final core mechanic of this build. Combined with the 1.75 cooldown reduction from a combined Insight and Blazing Fists, leads to the combo of this build. If you manage to basic attack the entire duration (Or close to it), the cooldown for Deadly Reach will have completely reset, allowing for repeated Deadly Reach's. Combined with the mana topup from insight means that you most likely won't notice much loss in mana.

Level 16: I personally go for Way of the Hundred Fists for the extra burst damage (which is fantastic in finishing a low health fleeing hero), but any of the other talents work just fine. Echo of Heaven can be good for some extra healing for you and your team, Cleansing Touch can be a lifesaver if someone nearby is stunned or rooted, as can Dash of Light if someone is low on health.

Level 20: Again, this one is entirely up for you. I personally suggest you pick the Heroic talent (Either Peaceful Repose or Transgression depending on what heroic ability you chose). If you want to mix things up or play a bit more defensively/tanky, go for Storm Shield. Epiphany is completely useless with this build due to the basic ability cooldown reductions (Radiant Dash won't have a long cooldown due to Insight) and the mana topups.
