About this item

This gorgeous gemstone is brimming with mystical, otherworldly powers that are beyond the comprehension of non-fictional characters. It is believed to be the true source of the Mythweaver's extraordinary, reality-bending magic and can therefore only be found by catching his purest and most powerful form.

If these phenomenal jewels were to be wrested from the Ultimate Mythweaver's relentless grasp then perhaps they could be used to craft wondrous and unimaginably powerful creations. It is also rumoured that there may be treasures contained within the diamonds themselves.
