1. You can't use the Weapon Finesse feat with a longsword.
2. You can't take the Weapon Specialization feat without FOUR levels of fighter AND Weapon Focus.
3. Gaseous Form makes it impossible for you to attack and do damage. It is strictly a stealth/locomotion spell.
4. Mage Armor doesn't stack with Bracers of Armor--both grant an Armor bonus.
If you're going to blither about how to build a mage who can function without spells, it helps if you actually know the system you're talking about.
A rules laywer...great.
Listen, I don't have the character sheet with me, so I'm pretty much talking from my memory - and it has been a few months.
The point isn't if I got the name of the feat right (it was Weapon Focus, not Specilization) or not, the point is that you can make a mage that can take care of itself in battle.
Also, who ever said using Braces of Armor and Mage Armor at the same time. I was saying that either is a possiblity.
If you want to build a truly functional 3.0 or 3.5 D&D fallback for an elven wizard or sorcerer, though, you pick up a longbow. No need for a feat, because the bow already uses dex for your to-hit bonus. Greater Magic Weapon, Bracers of Archery, and Tenser's Transformation can help make up for the serious base attack bonus deficit that wizards have (particularly at higher levels). And, of course, if you're 21st level or better, you can Shapechange into a Solar which gives you DR 15/epic and evil, fly 150 (good), immunity to acid, cold, and petrification, regeneration 15, resist electricity and fire 10, and spell resistance 32 just for starters. Not to mention +21 natural armor, +18 strength, +10 dex, and +10 con. Ahh, Shapechange. The original "I win everything" spell. Lasts all day. Lets you turn into any creature of less than deity status. So, so broken.
I know. But I didn't want that.
The character concept was a sword mage and Irolled with it, even if it wasn't optimal.
Casters being near-useless once they are "out" of spells is actually a DESIRABLE condition, part of a functional game balance in games where casters have many, varied, POWERFUL spells. It is the ONLY thing holding them back. Otherwise casters are absolutely the most powerful classes across the board no contest.
The question becomes "how useless".
