Hand of Balthazar - possible elite?

here is my idea of this skill

Smiting Prayers


Hand of Balthazar

5 energy
1 second cast
15 seconds recharge

Target touched foe is knocked down and takes 40...76[84]
and you lose 10...4[2] energy.

tell me wat u think thx

I think this is rather powerful...and abusable by every class.

It brings to mind-

However, not quite as many drawbacks. Knockdowns are a powerful form of control, and most knockdowns are either conditional (Stoning/Heavy Blow/Weaken Knees/Shield of Judgment), or come with heavy drawbacks (all adrenaline loss [Hammer Bash/Heavy Blow]), exhaustion ([Shock/Gale/Meteor]), long recharge ([Signet of Judgment]), etc. or a combination of both [Heavy Blow].

This has neither of those characteristics.
It's a cheap, unconditional knockdown with a decent recharge and no drawbacks. I'd suggest working some into it, or else it won't really come into line with existing skills.
Edit: Bah, forgot the energy loss - It's so meager I didn't really count it. Even with it in mind, I say the same thing.

It is also 5 energy at least, and 15 energy at most. I could see an E/Mo with earth magic being a viable way to spam this.
