>luckshit a good grandparent with the blue and pink sparks you want, can have any unique skill, this uma's parents don't matter
>use that grandparent (and a really good borrowed one) to luckshit another uma with the blue and pink sparks you want, this time with a good unique skill

if you want to grind forever and treat this game like a job you can also go for specific white sparks but i really don't recommend it, just get your skills from cards
