Okay I’m gonna formalize all this heritage transfusion stuff:
When you donate your heritage, you lose one of your heritage moves (the GM will choose) and you bodily transform one step closer to raw living clay, to the mean form of all sapient life. It’s up to the GM to decide what this form is, but it’s almost certainly not a two-legged mammal with opposable thumbs. Hope you were paid well!
When you receive a heritage infusion, you gain a heritage move appropriate to the donor. Then, roll minus the number of “native” heritage moves you currently have. On a 7-9, choose one, on a 10+ choose three.
You may choose the heritage move you gain
You permanently gain the heritage move
You do not bodily transform to resemble the donor
Your future offspring will be viable
You are not haunted by anxious dreams of your appropriated alien heritage
Fascinating.
