Skills will have a value between 1 and 5 and the caveat with the tree is that a higher epoch skill cannot have a greater level than a lower epoch. Where attribute raising will require you spend RP for the level you're going to, skills are simply 1-for-1.
I'm not sure if I like them being centre-aligned. I'll have a play with that another time.
