Hammer Thrower (5e Feat)

Prerequisites: Strength 13 or higher
You can throw hammers and mauls with great precision and velocity.

You gain proficiency in light hammers, mauls, and warhammers, if you do not have it already. Additionally, you gain the following benefits:

When you score a critical hit with a ranged weapon attack using a maul or a warhammer, you can roll one of the damage dice one additional time and add it to the extra damage of the critical hit.

When you hit a creature with a ranged weapon attack using a maul or a warhammer, you can use a bonus action to force the creature to make a Constitution saving throw. The DC equals 8 + your proficiency bonus + your Strength modifier. On a failed save, the creature becomes stunned until the end of your next turn. Once you use this effect, you must finish a short rest or long rest before you can use it again.
