Deific Weapon

You zealously bear your deity's favored weapon. If it's an unarmed attack with a d4 damage die or a simple weapon, increase the damage die by one step (d4 to d6, d6 to d8, d8 to d10, d10 to d12). If the weapon is uncommon, you gain access to it, and if it's an advanced weapon, you treat it as a martial weapon for the purposes of proficiency
