Question: Skills of the X all say that they add the color's skills to your class skills. But...

Otherwise, I really like it, except that, in order for a non-green/white, it costs you 2 of your 7 boons to pick up full BAB, meaning that if you want to have the highest rank boon from your color, you won't pick up full BAB until 16.

Personally, I would give Boons at the levels that Fighters get bonus feats. This kicks the total to 11, which means that you could get to Legend in 2 colors, or have serious mastery of a single color. Or even try doing a tri-color. As it stands, tri-color is nearly impossible and dual-color is pretty bad.

Give each color a spammable boon for if someone wants to be single colored.

Why do the Command boons not benefit the Planeswalker? I can understand it for blue (fundamentally better than the Medallion) and black (debuff), but the rest don't really make sense
