32 point, human. planning of acid savage. maybe acid\cold?
prefer solo style.

need some help with stats:
do I need 3rd skill (int10-12), or can I take cha 18 and con 18?
do I need str 10?

skills: concentration, UMD. Do I need to take tumble 1? at 1st lvl? if yes, instead of what skill?

spells: too many of them, hard to understand which should I take =)

same for feats/enhancements.

could you please help me?

I read a lot of similar posts, but mostly they describe fire or cold savage builds. Also, it it really hard to find up-to-date info when I see that many topics.
