You have trained in the ways of the wall defenders, who cut their teeth in fierce battles with the cruel and savage Southerners. You gain the following benefits.
Ability Score Increase. Increase your Strength or Dexterity score by 1, to a maximum of 20.
Trained Accuracy. Attacking at long range doesn’t impose Disadvantage on your ranged weapon attack rolls.
Flight Feller. The first time you hit a Huge or smaller airborne creature with an attack roll using a thrown or melee weapon on your turn, that creature must succeed on a Strength saving throw or fall Prone (DC = 8 + the modifier of the ability you increases with this feat + your Proficiency Bonus).
Wing Pierce. When you score a critical hit against an airborne creature, that creature falls Prone.
