请注意：它将伤害包括跟随者在内的所有射程。 包括J'zargo。 当我对其进行测试时，他仍在跟着我，随后对我发怒。 当然，会引起亡灵爆炸。
I tossed this together because I can't find any mod that does this specific, tiny thing. I know there is another way to reward spells from quests, but I am not that comfortable to be messing with quest triggers or scripts.
All this does is add a spelltome that teaches the player J'zargo's Flame Cloak spell, to J'zargo's inventory. So you generally will have to help him with his scrolls first before you can get it by having him follow you and simply grabbing it from his inventory.
Be warned: It will harm all in range, including followers. Including J'zargo. He was still following me when I tested it and subsequently went aggro on me. And of course, cause explosions on the Undead.
Obviously, this is a situational use spell that not everyone will want so available without console commands. But I did, so maybe others do as well.
