So I've just discovered you can sneak attack with spells... :D That's it, the half-elf is in, the little blond annoyance is out.
Just wondering. Is it worth to take one level as rogue on my wizard just to be able to sneak attack with spells? Is one level enough?
My guess is to go for the arcane trickster, but I have no idea what the reqs are and whether you even have to be a wizard/rogue. Other classes like magus might qualify too, and then there is this one alchermist kit that gains sneak attack. Tbh, I am still figuring out how basic skills work, so forget advanced chareacter building...
Arcane trickster is best if you build up on top of a real spell casting class such as wizard or sorcerer , reason being you get +1 level to an existing spell casting class which is far more powerful if you are adding progression to a class that progresses up to level 9 spells than a class that only gets up to level 6 spells such as Magus or Bard.
To qualify for the class you need 4 ranks in 3 skills (that means minimum total character level of 4) and level 2 arcane spells (wiz3/sorc4) and Sneak Attack 2.
You have two ways to get Sneak attack 2: 3 rogue levels and the one I favour the most 1 rogue level plus picking improved "accomplished sneak attacker" feat at character level 3 to add one extra dice to sneak attack thus saving two rogue levels so you will qualify fro Arcane Trickster with just a single rogue level and 3 Wiz levels, after Arcane Trickster prestige class is completed probably you should go back to your primary spell casting class to get level 9 spells asap.
*Sorcerer is workable too only you will need Rogue1/Sorc4 to qualify for Arcane Trickster but that's not going to mean a lot in the end since you will get to level 9 spells, just 1 level after wizard.
**Yes you can do arcane trickster with a mix of rogue, bard, magus, or even as a pure vivisectionist but imo those option are bad and you are better doing something else.
