at least it wasnt considered a crime in Oblivion or Morrowind so by that logic I assume its not a crime in Skyrim (unlike Fury which confuses me as to why its even a spell if i wanted NPC to attack me why not just attack them o.0)

So how do I get the spell that will allow me to unleash the power of the Mad God onto unsuspecting civilians ?

Frenzy is an adept Illusion spell. Depending on your Illusion level, it should become available for sale at any court wizard. You bought Spell books before, yes? Didn't you say you have a level 40 character? Also check the Mage's College. The Illusion trainer should have a copy as well, if you qualify.

Ah that would be why I cant find it My Illusion is Novice ... I really cnat find a use for any Illusion spell except for Frenzy and they removed chamealion ... is invisibility as a spell still available ?

Yea, invisibility is an Expert Illusion spell. I miss Levitation from Morrowind LOL Oh and Night Eye from Oblivion. Night Eye and Light were illusion spells in Oblivion, and I leveled up Illusion pretty fast using those two spells. I also don't find a lot of use for Illusion in Skyrim. I don't really use any magic here, besides restoration.

Pretty sure Frenzy counts as an assault.

I think calm is the only spell that doesn't make aggro. I am not sure if it aggros if it is resisted or not.

if Frenzy causes agro in skyrim ... again what use is Fury ?

Frenzy affects higher level targets, as well as affecting all targets in a nearby radius. Fury only affects the target you hit.

what o.0 ? no longer able to single out a single npc and make them go mad and then make everyone else in the area eitehr run away in fear or kill the mad one

(i made a war break loose in bravil once by useing frenzy on a single npc with no AoE )

With spells you would have to cast it undetected. It's much easier with the pickpocket perk that let's you drop poisons into NPC inventory.
