Weapon Expert

Benefits: Choose one weapon.  You gain the following...

• You increase either Strength by +1 for Melee weapons or Dexterity by +1 for Finesse melee weapons and for Ranged weapons, to a maximum of 20.
• You gain Expertise with that weapon, allowing you to add your Proficiency bonus TWICE to all attacks made with that weapon.
• When using the weapon, you always have the Mastery property for that weapon.

Example:  A 4th level Bard chooses to become a Weapon Expert with a Rapier.  As this weapon has the Finesse tag, she increases her Dexterity by +1, adjusts her attack roll data to reflect 2x her Proficiency bonus and records the Vex Mastery property in the weapon's stat block.
