I am working on an unseen seer with questionable ethics. The entry into the PrC is going to be sorcerer 3/rogue 2.
With a bit of work on making choices and declaring my basis of ideas with my DM I am going to go with the drconic heritage feats from an assortment of splatbooks. My progression ATM is:
1 sorcerer draconic heritage (blue), draconic claw
2 sorcerer
3 sorcerer draconic senses
4 rogue
5 rogue
6 unseen seer blue dragon heritage
7 unseen seer
8 unseen seer
9 unseen seer draconic legacy

After that I'll finish the unseen seer levels and go either all sorcerer or into dragonheart Mage or spellwarped sniper, I am not to sure yet. But the idea is to pull some stunts with ranged touch spells and sneak attack. Which way would latter progression be best? And am I on the right track for filling a rogues postion in a party also?
