Do "Discount" talk, have at least 40 likes with Northcrest soldiers, during the trip ignore his hand, in the cave rim him once, protect him from enemies, give him 5 stones, and that should give you the heart.
i aleady have 100 likes with the soldiers already, but so far, and almost 40 with the that dwarf, but no luck so far getting the hearth. I wonder if i'm missing something
Make sure you only do what I mentioned in the cave and nothing else. Talking with him afterwards while he's mining will prevent you from getting the heart.
When it comes to enemies, don't fuck them, beat them normally. I don't remember if submitting prevents anything.
