When i ate the leg, 3k xp. then Friend of a shark appeared on the waters near the original shark. it was also a shark. killing it yields 1k xp. funny thing tho, when i attack it it swam onland since its not aggro yet, i attacked with ruptured tendons, and it bled continuously until it fights me for real.
I play solo dwarf, got like 1000 items in my inventory after completing the whole reaper map, i keep everything i find, only sell things i'm sure i won't need. Can't find the damn leg, i guess it went into that white spider belly, i see nothing else. Is there a way to spawn items ?
It's been a month so I don't know if you're still playing this save, but the leg is inside a shark on the beach near where the lifeboat first drops you off on Driftwood. I think it was around X: 456 Y: -47. This is my first playthrough and I have pet pal so I don't know if you need pet pal or not, but probably not. You have to kill the shark and loot the leg.
