Chain abilities - How do they work?

[Cancermantis]

While I do find the wizard very useful at times, I must admit I can't quite figure out how the game decides between different targets when the attack moves from one enemy to another. There will be a nice path of three enemies to hurt, but the first one has another dude near him that pulls the lightning away from my intended target, resulting in two hurt dudes instead of three. Like this:
# # # D #
W# A # #
# # # B #
# # # C #

Instead of going A->B->C, it just goes A->D. I'm sure there's a logic to it, but I haven't been able to puzzle it out. Anyone have any ideas?

It's definitely one of the harder aspects of the game to understand, especially for the otherwise predictable Council team. Check out the Appendix of Hamlet's Mechanics Guide: http://iam.yellingontheinternet.com/2012/08/10/hero-academy-mechanics-guide

Here is several experiments from a Chinese Hero Academy form. Hope it can help.
