Blue cautiously lowered the stone in, not wanting to fail its master. It seemed to have trouble dispersing the necrotic mana, perhaps because it was not used to doing such a thing - an undead creature dispersing its own life force would be insanity in any other situation.
Yet Blue succeeded, and two roughly-shaped axes were formed, each with heavy axe heads. Blue grabbed one and felt the weight of its chopping end, bobbing it up and down in its arms and then giving it a swing before looking at the heavy axe head with the stone inside - needless to say, it was impressed by the simple trick of embedding a stone inside.
Jay decided to do the finishing touches himself while he had Blue watching at his side. He added some reinforcing bones between the head and the shaft, made the handle smoother, and ran his mana-infused fingers along the blade to sharpen it, then finally checked its stats.
