Black Rook Hold: Heavy, But Helpful

Objectives
Retrieve some Sabelite Sulfate from Heroic: Black Rook Hold, craft a Flask of the Countless Armies and return both items to Alard in Dalaran.
 * Sabelite Sulfate
 * Flask of the Countless Armies
 * Dantalionax Slain

Description
The next ingredient on the list will supposedly add strength to the mix, according to Deucus. I've heard of it before, but haven't really used it.

It's called Sabelite Sulfate, and it's said the elves of Black Rook Hold use it in their blacksmithing.

Something like that won't just be lying around. You may have to delve deep into the hold to find it.

And due to its weight, I made need a concoction of yours to compensate, something to give me a bit more strength.

Rewards
You will receive:
 * 16,450 XP
 * 16,450 XP

Progress
I hope Deucus was right about these ingredients. This'll be the first time I'm making something like this.

Completion


So this is the stuff? It's definitely true what I've heard. It is quite heavy.
