Doppelsoldner

Doppelsoldner were the volunteers from among the Landsknecht, choosing to fight on the front lines. These brave warriors were famous for their use of the Zweihander, Half-Plate and poofy hats. While you are wielding a 2-handed melee weapon with a reach of less than 10 feet, that weapon's reach becomes 10 feet. Additionally, while wielding a 2-handed weapon and wearing a poofy hat, you may choose to make a special Headbutt attack in the place of one of your regular attacks as part of an Attack action. This attack uses Strength, and you are assumed to be proficient. If this attack hits, the target must make a Constitution saving throw with a DC equal to your strength score, falling prone on a failed save.
