Myrmidian Warden

+10 Devotion

As a bonus action, you cause your bullets to thrum with the burning fury of the Mistress herself.
The next time you make a ranged weapon attack you within a 1 minute, the bullet transforms into a searing bolt of flame.
Make the attack roll as normal.
The target takes 4d8 fire damage on a hit, or half as much damage on a miss, instead of the weapon’s normal damage.
Whether you hit or miss, each creature within 10 feet of the target must make a Dexterity saving throw.
Each of these creatures takes 2d8 fire damage on a failed save, or half as much damage on a successful one.
Once you use this feature, it cannot be used again until you complete a long rest.
