You have practiced extensively and exclusively with one weapon, moving beyond specialization or fighting style to true mastery.
Select one weapon with which you are already proficient. When you attack with this weapon you may add your proficiency bonus twice. You can decide whether to add the second modifier to your attack after the die is rolled, but before the outcome is announced. If you did not add your proficiency modifier a second time on the attack roll and you hit, you add the proficiency modifier to your damage. If the roll is a critical hit you add double your proficiency modifier to the damage rolls.
Because of your excessive practice, you have neglected entire groups of weapons. If your weapon of choice uses your Strength modifier for attack and damage rolls, you apply only half your proficiency bonus (round down) to weapons you are proficient with which rely on Dexterity. Similarly, if your weapon of choice uses your Dexterity modifier for attack and damage rolls, you apply only half your proficiency bonus (round down) to weapons you are proficient with which rely on Strength.

Posted Aug 4, 2021I get the second paragraph is supposed to compensate for the overpoweredness of the first but it's not really that big a deal to only use one type of weapon. In lower levels this isn't super powerful but assuming you get to level 17 and have a proficiency bonus of +6 this gets to be ridiculous. +6 +6 +5 (likely by that level for main attack stat) +1, +2, or +3 for magical weapon (likely by that level) = 18 - 20 attack bonus.

Posted Aug 10, 2021Much like expertise in a skill - it is quite possible to get a bonus in the upper teens at higher levels. For a character that wants to specialize in a specific weapon - this seemed to fit the bill and match with existing similar game mechanics. The penalty to other weapons was intended to make clear this is a commitment to a specific type of weapon to the exclusion of a large group of others, thus lending a touch of balance to the feat. As a DM, what happens when your player's favorite toy becomes impractical or inaccessible? Likewise, the ability to switch between adding the bonus to attack roll or damage forces the player to weigh risk vs reward. I respect and appreciate the feedback!
