I want to try a wizard for a new alt. I haven't played a caster yet, and I don't have Warforged. I have 32 point builds. I've been reading Vienemen's Wizards Handbook and Tihocan's Wizard builds in his Revisiting Paths thread, and I came up with this:

I don't have any items included since I'm a new player and I don't have any of the items usually listed. I have not included any tomes since I haven't pulled any yet.

I picked insightful reflexes as a feat - so should I use the 2 build points in dexterity elsewhere? I know AC will not mean much, but Dex helps in some of the skills. I could add 2 to Str, but with the BAB for a wizard I probably won't be doing much melee. I could add to 2 Wis for +1 to will save and a few skills, or add 2 to Cha for UMD.

Should I put more than 1 rank in tumble? Are they better in hide? I'm hoping for enough ranks in spot to see the mobs sneaking up to hit me.

Are 11 ranks in UMD (+10) enough to be useful? I assume I can get enough items to make it useful. I've pulled some RR items that UMD 10 would allow other races to use.

I can take a spell focus at lvl 20 - just not sure which I want. I figure I'll have time to see what spells I like by then. Do you recommend different feats, or a different order?

I'm not too worried about enhancements as they can be reset fairly easily, although I'm happy to get any advice offered.

I'll pick the spells based on which ones can't be bought as a scroll and which ones I have - I started saving them for this toon.

Thanks for any advice.
