1 level of Cleric with Animal Domain empowered summoning to spam armies of powerful minions after Invisibility spell as Sorcerer, Death Domain as Cleric because Shadowdancer is a prestige class most builds take one level of for Hide in Plain Sight(which Invisibility spell does) and Summon Shadow(which Death cleric does too). 2 levels of Paladin for immunity to Fear(useful versus dragons and undead), to turn undead as level 2 Cleric, saving throw bonuses for having high Charisma as Sorcerer and to Lay on Hands for emergency heals and Smite Evil. Half-Elf for Immunity to Sleep spells, which human Sorcerer/Paladin/Sorcerer does not have and they will get immunity to Disease as level 3 Paladin but with 3 skill points in Heal you can cure disease and poison. Also, high bonus saving throws from Charisma make disease and poison rare. One more level of Paladin is one less level of Sorcerer. In addition, to have immunity to Sleep spell you can be an Elf but they get XP penalty as Sorcerer/Paladin/Cleric. Lastly, it's a power build that has high Charisma making it have natural skill points in NPC dialog so it's also a role-playing build.
Skills: Concentration, Lore, Spellcraft, Tumble(cc) 5 skill points at a time for +1 armor class, Heal(3 skill points at level 1)
Choose Pixie as familiar, has rogue skills and you can possess as scout to explore unknown areas disarming traps and unlocking chests/doors. Rounds out the build so that it's a Fighter/Mage/Cleric/Thief all-purpose character in D&D terms. Take Bull's Strength spell at level 2 in addition to Invisibility, pixie has only 7 Strength and you should buff its Strength before possessing. Also, Endurance spell to buff its Constitution because it turns it into a player character rogue and it's normally squishy. Summon pixie, cast Bull's Strength and Endurance on it, possess it then explore and attack with its +1 dagger. If it dies summon another one(summon before Resting to get 2 summons), repeat process and after it dies use Lay on Hands to restore the HP you lost. Then summon Shadow and cast Invisibility on yourself, remain invisible and let Shadow level drain enemies, it does not do damage only level drains, to do damage summon your empowered minions while invisible. Most spellcasters will run out of spells attacking minions, save one Evocation direct damage spell of each level for last to finish them off when they have no spells left.
Save one Invisibility spell as final spell. To retreat, then rest to replenish all your spells and lay siege to any survivors with rinse and repeat loop.
Recommended spells: All Conjuration spells, all Evocation spells, all Illusion Spells, all Abjuration spells and Haste spell for increased AC and spellcasting speed before the Evocation nuke spells. Take the Spell Focus(Evocation) and Spell Penetration feats to bypass magic resistance. Empower Spell feat afterward.
Stats I'm using(feel free to edit)
STR: 10 [Average]
DEX: 14 [+2 AC bonus in robes, uses Chainmail + Shield if using Still Spell feat]
CON: 8 [Toughness feat at level 1 to counter -1 HP penalty]
INT: 14 [Sorcerers need more skill points, low INT and Half-Elf makes human sorcerers with Quick to Master racial ability superior]
WIS: 8 [worst priest ever, takes Cleric level for Domain Powers as Sorcerer]
CHA: 18 [Best Sorcerer]

Note: Turns undead as level 2 Cleric, all level 1 undead are instantly destroyed, up to 2 undead are turned with all of them taking damage, and Charisma determines effectiveness. Bang for buck level empowering Sorcerer summons.
Undead are immune to Pixie familiar sneak attacks and it's further synergy.
Equipment:
Sorcerer Robes
Chainmail Armor(for use with shield and Still Spell feat)
Light Shield(can be used with robes with a 5% arcane spellcasting failure, other shields weigh more and incur greater penalty)
Sickle(Lightweight weapon, many are holy weapons and/or have useful enchantments)
Sling(ranged weapon that can be used with shield)
Sling Bullets
You don't have to take Still Spell feat, cast spells on yourself before combat begins then switch to chainmail, it's a useful feat but not a priority.
Set Robes and Chainmail in the quickbar at the bottom to switch.
