Halberd

This weapon is designed to fight foes who wear heavy armour, slashing helms, denting breast plates and slicing shields alike. The first attack a weapon with this quality makes each turn against a foe in Heavy or Medium armour gains advantage.

This weapon adds 5 feet to your reach when you attack with it.

Your weapon is capable of making thrusting attacks as well as its intended purpose. This allows you to deal the damage of your attack in piercing instead of its original damage type.
