Precision

You attained expert skill in precision for combat, granting you the following benefits:

• Once per turn, when you hit a creature with an attack that deals piercing damage, you may re-roll one of the attack’s damage dies, and you must use the new number rolled.

• When you score a critical hit (Nat 20) that deals piercing damage to a creature, you may roll one additional damage die when adding the extra piercing damage the target takes.
