the skills from your realm (there are four of them) start at 1, the skills from adjacent realms (two) start at zero, then you roll 6d6 and assign them to each skill, so when you’re actually in play everything will have at least 1. Basically you get d6+1 in each skill from your home realm and d6+0 for the others!
thanks so much! just to clarify further (though hopefully not muddying the waters), you choose one skill from each of your two adjacent realms, so a Bone Manipulator gets the four Bone skills (Fracture, Protect, Fuse, and Forge) each beginning with 1 and then chooses one from the adjacent Meat list (begins at 0) and one from the adjacent Brain list (begins at 0) for a total of 6 Skills, then rolling 6d6 and assigning each respective value to your skills. At the start of play, your realm's inherent skills will be valued 2-7, your adjacent skills will be 1-6. Hope this makes sense and I didn't make it more muddy!
