D&D 5E (2014) GWM+Longbow

[auburn2]

No worries. I’ll continue using the RAW for this because it makes sense and doesn’t do something stupid like assume you can GWM with a longbow

So you make a character expend an arrow to hit someone with a longbow? After all it has the ammunition property and "Each time you Attack with the weapon, you expend one piece of Ammunition"
