Now do you guys want to build a character sheet in one go as a plan or do you want me to lead you through it step by step?
step by step.
[x] Tao stat allocation
16 (+3) - Cha, the primary casting stat for sorcs
14 (+2) - Int, more skills the better
14 (+2) - Con, more HP the better
13 (+1) - Dex, dodge and aiming some spells
13 (+1) - Wis, will saves.
12 (+1) - Str, carry weight, only effect it has really for a sorc. (and not even that when we finally become able to polymorph into a solar every morning)
Since stats only give a bonus at even numbers the 13s can be considered as effectively 12s. the benefits it gives are slim, they are:
1. its cheaper to raise them to the next even number (but we won't, because that would be stupid. All 5 of our levelup stat points go into cha)
2. when we reach level 17, inherent bonuses can only go up to +5. So a 12+5 = 17 while a 13+5=8, meaning slightly bigger bonus then.
3. some extremely rare enemies can drain our stats and if a stat gets down to 0 you lose (coma, death, mindbroken, etc).
There is an argument to be made for int to be a 13 and dex to be a 14. it would give us +5%p dodge and hit chance (with those rare spells that require aiming and are good enough to be worth using). But I think the extra maxed out skill is just more valuable. We will be short of skills as it is as a sorcerer. Note that touch ray attacks are mostly kinda crappy and our aiming sucks shit as a sorcerer anyways (half BAB) so we would likely avoid such spells anyways and use spells that don't roll to hit instead. Also, the dodge is kinda meh too, without armor our AC is going to be so bad that it would not matter, we would have to stay out of the range of fire and use magic to defend ourselves. Flight + immunity from arrows is a fairly low level and cheap combo. As is glitterdust for blinding enemies. Mirror image, etc.
I wouldn't call myself an expert, but I do have a reasonable understanding of D&D 3.5 mechanics, admittedly mostly based on playing NWN 2 rather than actual pen & paper.
There are significant differences between the two.
Your plan is actually pretty good, but I can see how NWN would cause you to underestimate skills and overvalue dex.
NWN/2 was a grind fest where you soloed enemies, blasting was boosted, defensive spells nerfed (no flight, no intelligent combat), SoL spells nerfed, it had a monty haul syndrome (massive amount of OP items), HP was inflated, and the skills were changed majorly.
It definitely skews things such that skills appear less important and dex appears more important than it actually is.
That being said, this would not be a crippling flaw, just a slightly less optimized character
