I'm coming at kit modding as a rank amateur here - I basically tweaked a few existing kits in NI (and even that took me forever, since I don't have a lot of time to learn how to mod) and it's given me ideas probably way above my station... especially since I am clueless with WeiDu and would have no idea how to add a new kit to the game (a real shame you can't just do this in NI?! WeiDu seems so much more impenetrable, especially for us non-programmer-types)
I'm really interested in creating a sort of Arcane Trickster style class. I'm aware that the Mage/Thief exists, but I'd quite enjoy having something that gets a handful of fewer 'innate' spells (and doesn't just turn into a mage with a bit of thief utility as the game goes on) with the sort of focus on Enchanment that, well, Enchanters get with some illusion utility to really take advantage of that backstab ability too. Plus they get to benefit from the fast Thief levelling. I think it'd just make a weird, but not too OP combination.
Anyway - to the point - what I really want to know is if it's possible to give this potential kit an ability such that casting against an 'unaware' target gives them a bonus to overcome any 'save-or-else' spells. Enemies get a -2 or something like that? Maybe - if that's not possible - just a bonus if the caster is hidden or invisible or something?
I wouldn't really know where to begin with actually doing it, but as I said my time's really quite limited (and I'd rather use my precious few hours to play the game than mod it!) and I want to know if it's possible before wasting hours trying to accomplish it.
Help super appreciated :-)
