Well, I mean that's where the section from chain lightning came from. The FAQ has a space dedicated to it. Chain lightning is making multiple attacks, so any ranged + bonuses go off the first creature, then if each subsequent creature has any modifiers, those are applied to whatever die the target is on. The base will always be 5,4,3,2,1,1,1,1,1... However with things like lightning + or lightning -, they apply to the specific number it is on already. The example takes this into account. First hit would be base 5 against a lightning +2, for 7. Second hits a neutral target for 4 dice. Third hits a lightning + 1 for 4 dice again, since it's on base 3.
The ranged + also has that ruling Ahlano, and Chain Lightning is an attack making multiple attacks against different creatures so it only gets the ranged bonus for the first creature as well.
