Don't know if you have this change yet. I did the ailing walrus today. I got the loc from Alla--- it was totally useless. Their loc was (-62,-87) well today when I got the item it was (+68,+8) or very close to it. In the same room with Monk 1.5 guy-- except he is on far side of lake. Ailing is not far from the stone hut.
Ailing pops in pretty much any walrus spot it seems.. I'vefarmed so much ink there recently, its always changing spots.
I've seen it in multiple locations. Best bet is to just kill every walrus in the zone.
take a tracker too
The zone is so small there shouldn't be any need for a tracker. It might be nice to have, but it isn't a deal breaker.
