It's a sad fact in this imperfect, peach-impoverished world that sometimes you find yourself in the company of others who wish you harm.
You have a defense number from 0 to 6.
You may have been spotted first by another frame. If so, you have a spot number from 1 to 6.
Your attacker has an attack number from 1 to 8.
I'll explain where all those numbers come from later on. (Spoiler: from the dice you've rolled.) For now I want to talk just about resolving attacks.
Here's the all-important equation: Attack + Spot - Defense = Damage Dice.
So say that here I've got Captain Hattapon and her 6 hardass shock marines, and you've got some allegedly-free colonists in their ridiculous "hi-legs." One of them is tracking Captain Hattapon's mobile frame with a targeting laser and another opens up on her with those twin machine guns. Here are some possibilities:
6 Attack + 4 Spot - 5 Defense = 5 Damage Dice.
3 Attack + 1 Spot - 6 Defense = 0 Damage Dice. (There are no negative damage dice.)
8 Attack + 6 Spot - 2 Defense = 12 Damage Dice.
You pick up that many dice and roll them for damage:
- If Captain Hattapon's out of cover, a damage die hits her on a 5 or 6.
- If she's in cover, a damage die hits her on a 6, and hits her cover on a 4 or 5.
- If she's in cover behind another mobile frame, a damage die hits her on a 6, and the covering frame on a 5.
- If this had been a hand to hand attack instead, a damage die would hit her on a 4, 5 or 6(!)
For each damage die that hits her, she loses one of her systems. Once she's out of systems, she loses her white dice, one at a time. When the second white die goes, she's destroyed.
When one of my frames takes damage, I get to choose which system(s) it loses. It's small comfort! I was using those.
So say that you have the best luck you can really expect and you get 12 damage dice on her while she's out of cover. Of those 12 dice, it's likely that around 4 of them will be 5 or 6, so you'll probably inflict 4 damage on her. That'll leave her with only her white dice left - a catastrophic, disabling blow.
Or say that you get 5 damage dice on her while she's in cover. The order of damage is: cover first, starting with 4s, then the frame. So if your 5 damage dice come up 2 2 4 5 6, that first 4 blows bricks off her cover. Is the cover still intact? If so, the 5 hits it and the 6 hits her, but if not, now the 5 and the 6 both hit her.
Or crap, say that it's not a hi-leg with double machine guns it's a converted construction frame with a pair of repurposed jackhammers, and you just got 12 damage dice on her in a hand to hand attack. It's very possible that half of your damage dice will come up 4, 5 or 6, and you'll inflict 6 damage for a one hit kill.
As always, questions welcome!
