The separated halves burst into flames, but did not regenerate. For this move, Jake had pulled out all the stops.
The huge saber in his hand was made of pure Adamantium and the Words of Power "Godslayer" had been engraved on its blade. It had been forged in the last few days by excreting the much needed Adamantium after digesting copious amounts of earth, metal, radiation and heat. A Fluid Core embedded in the pommel serving as Space Storage, and provided by Hade, allowed him to adjust the mass and length of his weapon at will.
With two new Soul Classes, his Silver Soul Glyph of Blacksmithing doubling the attributes of his craft, his current stats, and his recent progress as an Aetherist, Jake had just managed to produce a substandard Advanced Aether Weapon. He had also included some of his Blood Essence during the forging process, so the weapon was also upgradeable.
As a reminder, Haynt and Kenway are not yet part of the Myrtharian Nerds. They didn't have the stat boost from United We Stand.
