Bats, Bats, Bats!
Bats, Bats, Bats! is a short hunting contract: obtain Bat Wings and return them to Keiun. You pick it up by talking to Keiun in Sweetwater Pass, and it unlocks at level 4 and above as a one-time quest.
The single documented objective is exact: obtain 4 Bat Wings (X/4). The quest text also tells you where to look - Bat Hollows can typically be found in cave environments. The Bat itself is a low-health, low-damage hollow with just two attacks (Swoop and Acid Spit), both parryable and blockable, so the fight is trivial at the quest's level gate; the grind is in the wing drops.
Bat Wings are listed in the community's hollow parts documentation, dropping from the Bats themselves. Rewards for turning the wings in to Keiun are not documented in the source.
