Arcane Sneak Attacking Prestige?

[fallensavior]

Are there any classes that add both sneak attack and arcane spellcasting other than Arcane Trickster?

I'm specifically looking at advancing an existing 3 Wizard/3 Rogue/10 Arcane Trickster to level 20.

Unseen Seer in Complete Mage is what you're looking for. You can get in with Rogue 4/ Wizard 1, or Rogue 1/ Wizard 4, or any combination thereof.

I would recommend going Psychic Rogue (http://archive.wizards.com/default.asp?x=dnd/psm/20040723b) 1/ Wizard 4/ Unseen Seer 2/ Arcane Trickster 10, and then finish the build with Paragnostic Apostle or Archmage or similar. With a single level of Psychic Rogue you can take psionic feats like Up The Walls (http://www.d20srd.org/srd/psionic/psionicFeats.htm#upTheWalls) and use Dorjes (psionic wands) of any power on their class list.

There's like a bazillion of them. Arcane Trickster, Unseen Seer, Spellwarp Sniper, Daggerspell Mage, Anima Mage, Master of Masks, Dragon Devotee, Imaskari Vengeance Taker, Magelord, Mythic Exemplar, Scar Enforcer...and that's not including the ones like Assassin that have arcane casting of their own instead of progressing another class's.

There's also Daggerspell Mage (Complete Adventurer, pages 31-36): 9/10 arcane spellcasting advancement, +3d6 sneak attack.

Note that for Unseen Seer you will want Practiced Spellcaster to negate the CL loss drawback.

Well you'll likely want that feat for most builds of this type, with the exception of Illuminium Rogue 1 / ... type builds.

If you get to change your magic source to divine somehow (such as with Southern Magician) Black Flame Zealot, Shadowbane Stalker and Eye of Lolth all work too.
