Parent Advice?

So with independent training finally being available, I’m finally able to put a little more effort into parent building (work would never allow me)

But having gone a year and a half not being able to put much focus into it, I’m not really sure what I’m looking for now 😅

I know HOW to make them, but how do I know what sparks my uma needs?

For example Maya, who has 10% growth in both speed, stamina, AND wit. I would think give her some power sparks? But with this new scenario we need to pile on as much stamina as we can from other sources because the gain from the scenario is nonexistent.

So if anyone can explain it to me, that would be much appreciated 🙏
