Personally I didn't even run around that much. If you hold the up direction before you load an arrow, it starts aiming at the top instead of starting in the middle. I used that to take explosive pot shots when a cluster of 4 stillborns spawned, killing 3~4 out of the 4 each time, also shooting the flesh bud with a normal arrow to pierce any stillborns in the arch behind it, then poking stragler stillborns from inside the barrier that were alone and not worth an arrow.
(Also if you get the saint wand first from the secret boss, you can just spam magic like crazy instead of only taking potshots here and there)
