So, I have no idea how to even begin to make this work, but I would really like to make my Sorcerer skilled with Javelins; at least to the point that they're able to be used in battle as a backup weapon.
So, any ideas here? =3
okay.... why? By the time you amass the necessary feats to be good with javelins, you'll likely be at the point where you no longer need a backup weapon.
So my advice to you is; pick up javelins. throw them if you are out of spells.
If you feel you must, pick up point blank shot and precise shot, then specialize in ray spells so those feats wont be wasted for you later.
It's mostly for flavor reasons, and that all makes sense. Now my question is, with such a low BAB, will I be able to hit?
on occasion.
As noted, it's OK at low levels but obsolete pretty soon. The advantages of a javelin are that you can get Str damage on it, it's cheap and has good range and damage for a simple thrown weapon. So at 1st level, by all means carry a couple if you haven't dumped Strength.
But otherwise, once you can afford it, you might as well get a crossbow which is better in most respects: a light xbow and 20 bolts weighs as much as only 3 javelins, has much better range, more base damage and better crits. And you can get specialty ammo. And the orcs can't throw them back at you.
About the only synergy I can think of with Sorcerer is that you can use Mage Hand to pick the thing up afterwards, provided you don't throw it too far.
