Every BeastHunter has a BeastAmulet. Your amulet allows you to control up to eight divine beasts, arranged in a square with four formations: fire, wind, earth and water.
At the start of the game only two slots are available for you to use; more are unlocked when you pass advancement tests. The final, eighth space is only available when you defeat Levant.
Each element has its own side, with a beast in the centre, protecting the BeastHunter. The other two slots on a side are shared between two elements. For example, the beast on the top left corner can be used on both the Fire and Earth formations.
