Arcane Trickster build for beginner?

[Arktanis]

I've also got various rog 13 / wiz 7 "Arcane Trickster-esque" builds, but they mostly predate the rogue overhaul in Update 25. The unfortunate side-effect of buffing the rogue 18/20 enhancements is they "reverse-nerfed" heavily-MCed rogue builds like mine. So it goes...

For sure, I prefer the higher Wizard levels, as Arcane Tricksters are typically ray spell users rather than assassin type, but with no SA on Ray spells, the higher wiz levels were closer approximation. Also gives you a larger spell pool to mix.
