Question: I'm not sure if this is covered in Heartbreaker, but do different soul types affect the game/ play style in any way?
They have no strict mechanical abilities or purpose in the rules as written- the intent being that a table/group is encouraged to use them creatively or for narrative fun as they see fit, how they see fit. Kinda similar to how hidden stats are up to the justification, use, and interpretation of the table using them xwx
