The Beat Goes On

Objectives
Create a runic power core and charge it from the corpses of Awoken Guardians and Vengeful Bones.
 * Collect Smooth River Stone
 * Enchant Runic Power Core (1)
 * Consume Souls (12)

Description
We have most of the materials we need, but we require one final item. A heart.

Don't worry. I don't mean one of flesh, but of stone; to bind the materials of the body into a single form.

Find a smooth stone, and enchant it to hold a life force. It will require some reagents, but I would expect a powerful enchanter such as yourself to have some on hand or know where to find them.

Once that's done, it will need to be powered. The souls animating the elementals and undead here should do the trick.

Rewards
You will receive:
 * 17,850 XP
 * 17,850 XP

Completion
That was the last item we needed.

Now we just need to go to my sanctum so we can assemble it undisturbed.
