Reliquary

A tiny box or other container holding a fragment of a precious relic, saint, or other historical figure that dedicated their life to walk the path of a true believer. A deity imbues the bearer of this artifact with the ability to call forth their power and in doing so spread the faith once more.

Spellcasting Focus. A cleric or paladin can use a holy symbol as a spellcasting focus. To use the symbol in this way, the caster must hold it in hand, wear it visibly, or bear it on a shield.
