Jas Shard

The Jas Shard is a piece of the Stone of Jas that was broken off before it was fully lost to a cave-in. It is used by Spiffy McSpoffinberg in order to stabilize the Godly Magic he obtained by killing Zaros.

Despite being a piece of the Stone of Jas, anyone who interacts with the shard only gains a fraction of its power. Additionally, it is typically only able to physically empower one individual at a time, meaning that Spiffy's allies are unable to gain the Stone's effects without taking the Shard's stabilizing benefits away from him. This limitation does not seem to apply to mystic or mental connections though, as when Ark Shine attempted to control Spiffy while he was in possession of the Shard the power feedback overloaded Ark's brain and ultimately destroyed his mind control ability.

The Shard is currently on Spiffy at all times, even when he sleeps, though he often hides it underneath his clothes or armor. He requires the Shard's constant flow of energy in order to remain in control of his powers, because humans in general are too weak to handle Zaros' godly energy. If he were to go more than a few hours without the Shard then he would lose control of his powers and likely die.
