I was looking at Mimic Power, and thinking that it might be a shortcut to building an uber-Sorcerer, the really powerful bit is the ability to just strait up replace your score in a skill with the rank of your victim's skill. It seems like a fine way to get lots and lots of skill points. Here is just a preliminary theoretical build to showcase what I mean. Note that under Mimic Power's Must, it only details needing to set aside mimic points, you dont even have a surcharge like with Modular Abilities, or any other powers.
