As an action, you can make a melee weapon attack with a weapon that deals piercing damage in an attempt to pierce the creature, traveling through to other targets.
If you use a pike or similar weapon, each creature in a line behind the creature and within your weapon’s reach must make a Reflex saving throw.
If you use morningstar, pick, or similar weapon, each creature within 1.5 meters of the creature and within your weapon’s reach must make a Reflex saving throw.
On a failed save, a creature takes piercing damage equal to the stamina die, or half as much damage on a successful save.
You can increase the damage for each additional stamina die expended.
