At lvl 7: Energized Cord is the go-to talent. You will generate so much energy by yourself you simply cannot take anything else. Peopl tend to pick Empathic Link, and ocasionnaly place the crown on a tank... Not only does it generate little energy, but your tank will not generate a lot of Energy with his damage, it's a trap.

At lvl 10: Crystal Aegis EVERYDAY and EVERY TIME!
Resurrect is garbage, it could simply be a baseline activable on Auriel and it wouldn't buff her that much, since the hero will usually die again.

At lvl 16: Wrath of Heaven is the go-to. If you pick Auriel, it's to go with a high damage dealer, maybe a mage of some sort. It will generate Energy faster, and give your team more damage! Reservoir of Hope can be good, but the tradeoff with increased damage is not good enough. And finally, Will of Heaven is the trap; in most cases, you DPS wants to move and stutter-step, but with more AA speed, they won't be as efficient at doing this, and it doesn't give you much value in general (there are exceptions though).

At lvl 20: Shield of Hope is the only Storm Talent you will ever pick. The ultimate ameliorations are not worth it, and the Angelic Flight is a ****ty talent if you consider it's a lvl 20...

Now that this is out of the way, let's review the builds!

Good value every time. Stack Increasing Clarity to increase your damage (meaning it gives you more Energy by yourself).
Repeated Offense is good for quick burst, but it's mostly picked for the additionnal 25% knockback.
It has good synergy with Piercing Lash, but you can switch to Blinding Flash if you need to.

This is if you want to get consistent blinds, as often as possible.
Righteous Assault will give you the lower cooldown, while Magestic Span will increase the area, meaning you will be able to play safer and get more cooldown reduction.

For the Quicker Blind build, we simply trade the cooldown reduction for increased cast speed with Swift Sweep. This is if you need to blind someone INSTANTLY (like a Taz'Dingo Zul'Jin).
