FUUUUUUUUUUUUUU
This whole time I've been waiting to get the Pharalus (or whatever) bow. Not because it's awesome but more of I just wanted something with an S rank.
I didn't know where it was exactly I just knew it was in the Darkroot. So after poking around there, beating Sif and searching everything and not finding the bow I looked it up. Looks like the computer enemy with the fog ring and the bow drops it. Too bad she fell off the cliff before I could kill her (I was one hit away too, she rolled backwards and poof).
Oh well, will have to get it in NG+ but I wish they really would fix that. if enemy dies in unreachable place, put loot up in reachable location for ALL loot.
