I wish I had done such an analysis myself! LOL
Right so the dice to roll for an effect is based on the number before the d6 inside the power effect. If you read the included PDF it will give you some simple steps to create and import a character so you can try it out. It's easy to add more dice to the roll by right-clicking once you have the dice picked up. This is great for Haymaker's or other sources of added DCs. What's a real pain is if you need to roll less dice. The only way to do that would be to edit the power description... Ugh...
FG is kinda hard to get the hang of. The roll has to be packaged up, which includes the actor and the target(s). After rolling, there's a results handler which includes the number shown on every die. This lets you count up normal damage body and stun separately. I included other info in the roll like attack type and damage type to help determine which defenses to apply and such. I think this is in "damageHandler" or some such function.
Also, FG allows ruleset layering. The CoreRPG ruleset already had a lot of what I needed just to get started. So, I based it off of that. This provides two benefits: lower ruleset size and automatic updates from CoreRPG. If you can't find where a function ends up from my ruleset code, try searching for it in the CoreRPG ruleset instead.
Good luck!
