Well, I just wanted to ask if somehow record is kept for every player that gives Surtami corpses, or if she just hands out the gold to the first one that gives her the 50th, 60th, whatever corpse?
Because sometimes I give her two whole spawns of the tower and don't get anything, and sometimes I give her only ten, twelve corpses and then I already get it.

She counts, but she also resets the count periodically, so it's all down to the luck of the timing. I think it takes two complete spawns exactly... but that includes the krokani you probably aren't finding. Or two and a half or so, if you don't get those.
