Burning Powerstones - 200 spell power to weapon

Yes these are truly awesome - last 4 hours even thru death.

Here is what is required to make them -
1 caramentium bar + 1 brilliang diamond = 1 diamond gorget

Artificer crushes neck and gets a random amount of salvage parts - 1-4 gem bits (cant remember the name), sometimes another caramentim bar, sometimes another diamond. Takes 5 gem bits to make one reclaimed gem - 2 reclaimed gems makes a burning powerstone.

This is a best guess based on making some of these for my casters:
-10 caramentium bars, and 10 brilliant diamonds - yield approximatley 4 burning powerstones.

Since they are not on the market place yet - if you need - send mats (shown in above paragraph) to Mirabeilla on guardian side - or erollos on defiant side and I will try to get as many of them for you from your materials as I can.

I believe they are selling for 4-5 plat on the AH, so gathering your own mats for them is definitely your cheapest option.

To be more specific... they can be made with anything that uses brilliant diamonds, or lightsbane diamonds. Each item yield 0-6 (most I have seen) go the glimmering shards (or gem bit, in case that isn't the name). I used about 22 diamonds, and got 15 powerstones out of it. Results may vary.
