Piercer

You have achieved masterful footwork a penetrating precision in combat to complement your strikes, granting you the following benefits:

• Increase your Strength or Dexterity by 1, to a maximum of 20.
• Once per turn, when you hit a creature with an attack that deals piercing damage, you can reroll one of the attack’s damage dice, and you must use the new roll.
• Once per turn when you hit a creature with an attack that deals piercing damage, you (and your mount if you are riding one) may move 5ft to an unoccupied space. This movement does not trigger Attacks of Opportunity.
• When you score a critical hit that deals piercing damage to a creature, you can roll one additional damage die when determining the extra piercing damage the target takes.
