Reinbeast is a Force affinity Epic champion from Skin Walkers faction. His passive is a unique one, that enables shields after damage is dealt. This in mind, he is useful in early game arena defense. However, beyond that he does not serve any real use in game currently, and with him being a defense based champion, the shields are not generally large. With all this in mind, he’s better off being left in the vault, as early game arena defense is not a focus for the average player.
