While attuned to the bow, you are considered proficient with it.
On your turn, after you make an attack roll but before the DM determines the result, you can cause the attack to hit unerringly, regardless of cover or whether the creature is around a corner.
The bow produces its own ammunition, which disappears after you hit or miss.
Lore: these bows were created specifically for birdkin races, such as aarakocra or owlin, but it was made by the aarakocra first so the item bears that race's name.
Proficiency with a Longbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
This weapon has the following mastery property. To use this property, you must have a feature that lets you use it.
Slow. If you hit a creature with this weapon and deal damage to it, you can reduce its Speed by 10 feet until the start of your next turn. If the creature is hit more than once by weapons that have this property, the Speed reduction doesn’t exceed 10 feet.
Notes: Aarakocra or Owlin, Combat, Ammunition, Heavy, Range, Two-Handed, Slow
Feels like you meant to put a constraint on the special ability something like once per SR or LR or perhaps charges?
The bow that never misses... uncommon rarity, of course.
Dang, I knew I forgot something. Oops. And this is my first creation. I would've made something like a heat-seeking missile but D&D characters likely aren't going to have that sort of thing.
