A Primordial Monster is a Monster unique to each Ethereal Islet created using all five Ethereal Elements. Each Primordial is representative of the corresponding Natural Element that is paired to each of the 5 Ethereal Elements.

This Monster makes it possible for all Monsters of its rarity to be affected by their 'Likes' placed anywhere on the Islet, a power shared by the Unity Tree on other islands.

Rare Monsters on the Ethereal Islets will need their Likes to be placed next to them, as they are not affected by Common Primordials.
