Signature Weapon (Skullduggery)

Choose a weapon in which you are proficient, such as Longsword or Spear, and for which you have learned the Weapon Mastery property of the weapon. That weapon becomes your Signature Weapon.

 While using the weapon one-handed, you can replace the Weapon Mastery property with another mastery property you have learned from a weapon you could also use one-handed.

 While using the weapon two-handed, you can replace the Weapon Mastery property with another mastery property you have learned from a weapon you could also use two-handed.

 When you choose this feat, choose one additional benefit you gain while wielding your Signature Weapon. You may change the perk you choose whenever you gain a level.

 Strong Arm. Your Signature Weapon gains the Light property while you wield it, unless it has the Heavy or Two-Handed property.

 Practiced Strike. Add 1d4 to the damage of a suc-cessful weapon attack with your Signature Weapon. 

You may use this ability a number of times equal to your Proficiency Bonus. These uses refresh when you finish a Long Rest.

 Critical Damage. When you score a Critical Hit with your signature weapon, add your Proficiency Bonus to the damage.
