When an animal consumes a magic source it may turn into a magic beast.

If a beast consumes a mage or a magic beast, it has a 10% chance of turning into a rank 1 magic beast. If their prey was a primordial mage or a magic beast, the new magic beast is of the same element as their prey.

If a beast consumes an Ether crystal it as a 1% (01-01) chance of turning into a magic beast of the crystal’s element and 5% (96-100) chance of dying.

If the beast’s prey was a non-primordial mage, or if it consume a neutral Ether crystal, it’s element is determined at random :
