That's a good build, Chumsie, but you could probably even go for Rank 2 in Witchcraft and Aerothurge for an additional 2 Novice and 2 Adept skills and look for some bonuses to INT to make them usable. An extra 4 ability points for 8 more slots of utility sounds like a good deal if you're already heading that way.
Thanks.
Honestly I don't see why you'd want to splash that far into either school. Witchcraft Adept only gives you one skill that isn't a debuff, and they need high Int to bypass resistances, and the final spell is a summon, which costs a bit too much AP to be worth using on a non-caster character.
Aerothurge gives you Summon Air Elemental and Invisibility, however. Both of which are great skills to splash for, although the elemental is a bit expensive AP-wise. The problem being that Guerilla no longer triggers the Invisible buff (because a situational +50% damage is apparently overpowered but Rapture isn't, or something like that) and that you already have Invisibility in the form of Walk in Shadows. The Elemental is only really useful because it can cast Feather Drop. But then again, Feather Drop is really-really useful.
Personally I'd just splash a single point into each of the other magic schools, if I were to dabble more into magic. Mostly for the sake of the Avatar spells, which are amazing. A lot of people tend to overlook them, untill they realize that the Avatar spells also clear the named debuff from ones target.
Bless(!), Midnight Oil(!), Fortify, Wildfire, Firefly and Rain(!) being a number of other great options for a Shadowblade. Rain in particular if you decide to go for Blitz-Bolt over Teleportation. Really, anything which dosen't need Ind-based stat-scaling to work.
But it does feel a bit odd for a shadowy assassin to be blessing people with the power of the Seven. Even if the 30% hit chance is awesome. So annoying to have somebody dodge you, just to turn around and face you.
EDIT: Also, I have no idea why my text-codes won't work. That quote should've been a quote, and not just text surrounded by parentheses.
