Bloodsworn
The powerful bloodsworn ability is a mystical bond forged between a Paladin and a Priest that binds the two together, granting both members great strength and great peril. To bloodswear requires much training in the sacred skill of Devotion, for it is its transcendent ability.
Perhaps the most well-known bloodsworn bond comprises the deities Aurora and Deucalion, who are known colloquially as the Bloodsworn Gods.
