Well, since you need to pick 3 more feats how about making Persuasive one of them - you already focus on both the relevant skills (max ranks in Bluff and Intimidate)?
I'm also stuck at feat selection. I picked Skill Focus for level 1 but don't know what to choose for the human bonus feat.
Ok, that sounds cool. Male Drow neutral-ish PC-Expert 6/Wizard 1 is my idea. I would have a level of cleric or bard to get some healing in (especially with the flesh-crafting idea), but wizard is the only spell-casting class that is favoured for male Drow and I believe that every Elf should have at least some magical talent!
