Aside from what I've already put forward I guess the most I can give you is a bit of a history for the character. So here goes:
"Herman Ferman (sounds great when he announces himself in his old man voice) has a family history littered with those who had a passion for stargazing. At some point in the past one of his ancestors reached out so far in his exploration of the heavens that some of that starry magic was imparted upon him. Since then that beautiful and sometimes violent magic has presented itself in various ways down the family line. In Herman it has presented as raw magical ability (as well as a hobby-like interest in the celestial bodies).
His abilities presented at a young age and in his early twenties he joined a group of adventurers dedicated to maintaining the peace in the lands around the small town in which they lived. Of course he eventually settled down, opened a small magic shop (simple potions, things that were of general use to the townsfolk) with his wife and had two sons.
Now Herman's wife has passed and his sons have grown, one of whom has taken over the shop. Herman has found himself alone and troubled by a "feeling in his bones" that something dark is coming. Never having been one to sit around and wait Herman has left his home and learned of a group of adventurers that have been doing some good of late. Though he'll have to re-learn some of the sorcery he knew in his youth, Herman will soon be asking to join these adventurers so he might face the darkness head-on rather than sitting by himself in his old home."
I was definitely going to take Use Magic Device as one of my skills. Also gonna take Knowledge Arcana to round out a bit of a gap in our party knowledge. Probably a few ranks in Appraise and Bluff (makes sense if he used to be a shop owner). Don't need perception as two of our party already have insane numbers there. Beyond that I'm open for advice on skills.
I'd like to keep my spells fairly balanced. I don't need tons of damage, some would be nice. Weakening enemies and making them vulnerable is a definite plus. A few utilitarian spells to round things out would be good.
Feats I'm really stuck on. Do I go for survivability, maximizing my spell abilities...what? Beyond Eschew Materials I believe I have 3 feats to choose (lvl 1 feat, human feat, and lvl 3 feat)
@Jus me - Thank you! That was all incredibly helpful as well as quite amusing.
