Yeah, I wasn't planning on doing any crafting shenanigans.
And are you positive about not allowing LA races? I'm perfectly willing to play without the possibility of LA buyback. That'd mean that, while initially I'd have good stats, I would hit level 2 (class level, rather than ECL) at around the same time that the rest of the party is working towards level 5, and would continue to be in that situation for as long as the campaign went on.
I swear up and down that I'm honestly really interested in the RP possibilities here. Heck, it's why I'm avoiding all the craft/UMD silliness Warlocks can do, as well as the much-better melee builds with eldritch glaive/claws (or, for that matter, just building a CoDzilla or primary-caster Wizard). I'll still have nothing to attack with but my 1d6 damage blast when the average party level is ~4.
That's what my sheet looks like now, and what it will continue to look like for a long darned time. No new feats, no new invocations, no damage increase on my blast, nada (and even if I get a decent stack of gold, my carry weight is so low that I can't do much with it). The ability scores are nice, but warlocks are one of those classes that can dump anything and everything and still do well, and they don't actually help me affect the flow of battles. Not to mention that PC Pixies don't actually gain any racial HD. It'll be hard to catch, but that's about it, and anything that actually locks me down will end me. I just want to fly around ringing my bell and hitting things with little pinprick glowing rays. :3
As far as the character goes, see the personality and other notes for what I'm going for. It's distinctly suboptimal without LA buyback available, but I think there's a lot of potential for fun there. The way it'll break down is that I can have fun RPing with everyone, won't do much in combat (but won't get splatted like a bug unless something gets a lucky roll), and can do scouting/party face stuff.
Pixie. -- Note that I took the version without Irresistible Dance 1/day, because holy shit even for an additional LA+2 that is fucking OP.
A good explanation of LA.My invocation and feats are both core.
