When something stacks in Cybercore, you simply add them together this can be a fix number or another dice. You simply add or deduct it from the result.
For instance Boosts (a +2) stack, so if you have a two Boosts (Boost(2)) they add together to grant +4 to your roll.
Certain dice or conditions Increment the size of the dice you roll. For instance, if you have a Boon from a single source, you roll a d4. If you have two Boons, you roll a d6, and so on.
So a Boon from multiple sources increases Dice size by one for each additional source.
1d4 => 1d6 => 1d8 => 1d10 => 1d12.
This pattern repeats for each additional source above 5 so for instance if you had 6 People helping you you would gain a 1d12 + 1d4 to the roll.
This is a great mechanic for GM's to use when they want to give the players a bonus from outside help, say a they have incited an Angry mob as a distraction while they sneak into a secured area. It's dosn't have to Increment on a single person, for every 5 people it could increment the Dice size by 1 so a Mob of 20 grants a +1d10, it up to the GM to pick a number that makes sense for the situation.
This allows for what might seem like a High DC Challenge become a little more manageable, while still keeping the risk of failure high.
Mob Of 20 Angry People = Inc 4 Scouting the Complex = Inc 3 Complex Blueprints = Inc 4 Bribing the Guard = Inc 5 Looping the 3 Security Cameras = Inc 3 Injecting a mild sedative into the drinking fountain = Inc 2
Total Inc = 4+3+4+5+3+2 = 21 21 / 5 (1d4 => 1d12) = 4.2 => 4d12 + 1d6
So 1d20 + 4d12 + 1d6 will average a DC of 40 even before you account for the squads Stealth
When players roll Social dice, they roll them hidden and at there choice may lie about the result.
The GM can call em out on it...
If the GM calls the player out and he's wrong the Player gets one better success, if the GM was right and the player was fudging his roll, a calamity occurs.
Certian Abilities, grant you the power of a flashback. These allow you to flash back in time and make a small adjustment to the time line.
Did you leave the stove on? Forget to tell you mom to put that cat out? Forget to buy some ammo for you Zigon Bug Splatter?
Never fear a Minor flash back can fix all those pesky inventory and know how mis-haps. Maybe you have the choice of the Red fruit, Blue Fruit, or Starvation? You really did ment to look up The Survivalist Guide to Weird Green Planets before you left...
Well now you have! Maybe you literally jump back in time for that single item shopping extravaganza! (and when you got there it was on sale! bonus!). Perhaps that package you didn't open that the mailman passed you as you went out the door was a copy of The Survivalist Guide to Weird Green Planets, from your Bro Joe! You did mention to your Bro Joe that you liked that book! Hey look it's even signed by the Author! Your Bros 'The Man'!
However you minor Flashback works it's sure to get you out of a Jam when the bugs are coming and the chips are down, before they eat you alive.
Oh wow you are using a Mojor Flashback!, Seriously really? The Time Continuum Authority are going to have words to you when you get home. Was missing that Black Friday Sale really worth it? What you fell over board in Powered armour while fighting a Nebruim Maw Crusher and
You know that's really not that serious a problem... are you sure.... you want to burn this....
Ok Ok fine! Don't blame me if the Time Cops toss you in a Temporal paradox where you get a knee to an organ repeatedly for the next ten years. I'm sure the Flash Back will be worth it.
Talk to you group, write down what you need, Tell the DM what you do, and how it happens, and how it doesn't FuBar the current timeline. You get one shot at this, failure will incur said Time Continuum Authority applying said Knee to said organs, (when you get back from the mission of course, they would never interfere with a Corporation sanction mission...)
They can wait... they have time...
