Allatos' Divine Touch

The caster calls forth the purifying flame of Allatos and places this blessing upon the weapon touched. For the duration of the spell the weapon deals a bonus 1d4 Radiant or Fire Damage, chosen by the caster when the spell is cast. If this spell is cast on a ranged weapon that uses ammunition the benefit is transferred to the ammunition when fired from the weapon.    

When cast with a spell slot of 2nd level or higher the caster adds an additional 1d4 damage of either type for each spell level above 1st they use to cast the spell.
