Update:

I went the Warchanting Path, my stats are:

Drow Lv. 4;
16 STR, 16 Dex, 16 Cha, 12 Con (+2 Con on ability upgrades);
Feats: Power Attack; Toughness

I'm really enjoying this character, great solo ability, useful in parties and stuff, now I have one last question:

I'm having doubts about going TWF: On one side, the Shortsword/Rapier enhancements from Drows are great, but it costs 3 feats and I don't know if the damage compensates it (Does it?) Also, I have +13 Bonus even without TWF (Only self-buffed) and I hit just fine. What should I do? Thanks in advance
