I like really low-end character builds that are overpowered in some way. All characters need to be able to do something well, so I tend to like them doing either one thing really well, or a bit of everything. I'm not an awful roleplayer, I do my best to play as a party member, but I do like having a bit of a killing spree sometimes. I mentioned the "High-dex Human Fighter with a spiked chain and a bow" build in the other thread, here's one that is sort of on the other end of that.
Random broken build #2.
Healy-healy, stab-stab.
This one uses 3 different core books from 3.5ed(PH, Complete Divine, Races of Destiny), so it probably should be a bit mucked up. There's even worse skills, classes, feats and combos between these three books, but this one is sort of a fun build. It caps out it's power-level at about 5th level, then you decide to go either the caster or rogue route, with either one being a nice addition to the other. It relies on high dex to do everything, so it's a bit of a glass-cannon in some situations. No dex bonus? Ouch. But there's nothing like a combat cleric of stabby doom
"Uurkrau" Illumian Rogue/Cleric of Fharlanghn
Place dex as your highest attribute, max the standard combat rogue skills (tumble etc, make sure your skill in spellcraft will be at 4 by third level), take a level of cleric at third level and choose celerity and travel(or time, forget which book that domain was in) as your domains. Grab "Practised Spellcaster" as your third level feat. Keep levelling as a rogue until fifth level.
You end up with +6 casting level spells(total 7th level at 5th) spells running off dex for bonus spells, +10 foot movement, a freedom of movement effect, Expedious Retreat for combat tumbling (70 foot movement for 7 mins, 70 rounds, when wanted), Longstrider for those long journeys, plenty of healing if needed (up to 3x(1d8+5) if you don't need combat movement boosters) and all the things that normally make rogues cool. Basically that one level of cleric and Practised Spellcaster gives you +4 caster level for level 1 healing and movement spells on top of your +2 Illumian bonus. Rogue+fast movement=good.
You then just decide if you want to stick to a rogue for the rest of your development or chuck in some more cleric levels for better and more spells. Any reasonable level of dex will give you free spells as your spell-level increases, keeping you up with the pack even though you're multi-classed.
It's not one dimensional either. Fharlangh is a pretty sick god who actually likes you wandering around doing adventurer-type things, you can change your spell set when needed (7mins of expedious retreat is aways handy), and you're a boon to any party with your rogue skills and high movement sneak attacks. It's a bit of everything, with a place in the world (wandering around for a god, healing stuff, stabbing shit and finding new stuff), with other role-playing chances too. You can scout, you can sneak into places as a tumbling-entertainer, you can shoot a bow, you can help people with their troubles, and eventually, you can be a bad-arse combat cleric if you so please. Stacking a level of sorceror after 5th level is nice as well, just for the extra spells and stuff you get.
Just one of those nice "do-everything" builds. It's not that focused, but by 3rd level your party has a REAL multi-skiller with heaps of growth potential. A sorceror/cleric combo can be done instead of the rogue/cleric combo, but stabbing stuff with rogues is more fun than having a few more spells.
This is why "Practiced Spellcaster" and Illumians are so broken. +6 Caster level, bonus spells off a combat stat, all because you decided to not level into a spellcasting class properly.
