Interesting turn of events.
I understand Resoonman being the result of my hit (while we have perfect aim, Roosesman rolled a 1, so I get placing him in the middle of the shot works as punishment), but where did the collateral damage part come from? I rolled a 3, so my shot should have gone as planned: a focused beam. I could see it being counted as "oh shit, the shot went through him and destroyed the land beneath him super deep," but Roesman didn't have any artifacts for causing deflections and whatnot. I would also understand if I spread my shot out, or rolled a 6, but a 3 seems a little too...ya'know. It just seems like an unnecessary add-on.
(and yes, I have absolutely no idea how to spell your name Rosey, and don't want to go through and find it. Hopefully one of those were right).
Ninja edit: I would also get it if Rosie O'Donnell rolled a 6 for defense and the shot was scattered.
It's mainly a difference in rolls interpretation. Here is how I envisioned everything :
Your [3]: Your attack is going normally, focused beam and all. Nothing more nothing less.
Resoon's [1]: He is going to get hit by the shaft, so let's make him appear in front of the beam.
> [2] [Here is how it heavily diverge] To me, this [2] meant: make everything bad for Resoonman.
So because Resoonman wanted to hurt Innanis, I interpreted this [2] as "protect Innanis accidentally".
Then the Collateral Damage was a separate roll mixing kick'n giggle and seriousness. Here is what would have happened depending on the rolls for Collateral Roll:
[1]: Something make it so the attack will somehow possibly affect a lot of places (the beam scatter into many beams upon touching Resoon/the Shield)
>[1-3]: Land glassed
>[4-6]: Some surprise
[2]: Collateral damage to one random known place (the beam goes through or is deflected)
[3]: Some minor collateral damage, nameless land busted (the beam goes through or is deflected)
[4]: No collateral damage
[5]: No collateral damage
[6]: No collateral damage
>[1-3]: The energy wave emitted somehow negatively affect many places
>[4-6]: The energy wave emitted somehow positively affect many places
Overall, you are rather right. The way collateral rolls was explained does seem like some sort of asspull, seeing as you said, Resoon had no deflection artifact or what-not. I could justify it by saying "But he shielded himself reflexively and accidentally created a deflection !", but if such an explanation is accepted or not depends on everyone.
tldr: Collateral roll determined beam comportement. Was probably a bad roll from my part, if so, sorry.
