The destruction spell, Chain Lightning, is described as a:
Lightning bolt that does 40 points of shock damage to Health and half to Magicka, then leaps to a new target:
How many times does Chain Lightning 'leap' to a new target? Will increasing the Destruction skill or getting certain Destruction skill perks increase the number of Chain Lightning's 'leaps'?
Does it hit non-hostile enemies? Does it have a priority of any sort when it 'leaps' (e.g. like hitting enemies first, before non-hostiles) or does it simply choose the nearest reachable NPC or creature?
