Scrawny Heavy Weapons Enthusiast

Prerequisites: Small size or a strength score less than 8.

You are an expert in the history, maintenance and use of heavy weapons, but lack the brawn to wield them effectively. That doesn't stop you from wading into combat with the biggest stick you can heft.

You gain the following:

• You are proficient with all weapons that have the heavy property.
• Whenever you make an Intelligence (History) check related to the origin of weapons or siege equipment, you are considered proficient in the History skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus.
• Over the course of a long rest you can spend time carefully maintaining, honing and improving a single non-magical weapon with the heavy property, that weapon gains a +1 to attack and damage rolls until the end of your next long rest.

When you make a melee weapon attack using a weapon with the heavy property on your turn, you can choose to make an all-out attack, throwing your entire body into it. Doing so has the following effects:

• If you are small you ignore the heavy property of the weapon.
• If your Strength modifier is negative you do not add it to the attack and damage roll.
• If your attack misses, attack rolls against you have advantage until the start of your next turn.
