Now to dip the other two, first the Spymaster will give me 11 skill point per level (I should have some rogue skills and knowledge Arcana and Religion to play my roles, yes?) so I think I will take it to level 3 to get Cover Identity, Undetectable Alignment (Important in my profession) Scrying Defense (I doubt changing diguises faster will me that much to a Doppleganger like me), Magic Aura (to hide my rings, cloaks and whatnot) and Sneak Attack in case I do need it (I deal in Information and Disinformation, not bodies My Lord)
