Prerequisite: goblin.
As the MM orc racial ability.
You have a deep and abiding adherence to the True Faith, and have firmly rejected paganism and the arcane. All divine spells cast on you are treated as if the spell was cast one level higher than it was. As an action, you can attempt to hold off arcane creatures through the power of your faith. If you succeed on your spell attack roll against their Wisdom saving throw they cannot face you or approach within ten feet of you for 1 round.
Once you take this feat you cannot progress in levels as an arcane spellcaster without losing your faith. If you lose your faith, you can swap Devout Belief for another feat, but cannot take the Devout Belief feat a second time without atoning. Clerics and paladins who lose their faith also lose all class abilities and spells and cannot progress in levels as a cleric or paladin until they atone and take the Devout Belief feat a second time.
Prerequisite: dwarf.
As the PHB dwarf racial ability.
You have an affinity for the arcane powers of paganism and sorcery (though this does not stop you believing in the True Faith). All arcane spells cast on you are treated as if the spell was cast one level higher than it was. Arcane creatures are more likely to like you (or at least make you their servant and not kill you when they kill your friends), and their starting attitude towards you is shifted one step towards Helpful. You know your True Name, which means certain magical effects (such as revivify and reincarnate) work more reliably on you if the caster knows your name.
