So I'm getting started on an Unseen Seer character. Given that I want to do this one with no lost CL, I'm taking the Ruathar PrC (from Races of the Wild: ridiculously easy to get into). Here are my current concerns and bases.
Human Wizard X(5?, conjurer specialist)/Ruathar3/Unseen Seer 10/X the rest
Attributes will be rolled, so I can't disclose those.
Pretty much everything is open here (except that the very first feat taken WILL be Able Learner, and that I'll take up Practiced Spellcaster eventually).
My current concerns are:
A) Early entry. Whichever method I can use to get into Ruathar early eventually pays itself off as it allows me to enter Unseen Seer a little earlier - and most of the really nice stuff in Unseen Seer is best used at low levels.
B) Getting ways to Persist stuff. I want to be able to Persist that lovely sneak attack spell (can't remember the name at the moment) before getting 8th level spells. Almost any method for doing this should be doable without CL loss (unfortunately the spell only lasts one round so Extend + ridiculously high CL doesn't work). I'd like to avoid Incantatrix if possible since I'll already be banning two schools...
Any help is appreciated. Links even moreso.
