There's a thing called a DRN (a Dominions Random Number), which is used for almost everything.

To produce a DRN:
- Roll 2 dice
- Add them, _but_, if either of them is a 6, count it as a 5, and roll it again, adding the new total. Repeat as necessary.

So, as an example:
- You roll a 6 and a 4
- That totals 9, but you need to roll the 6 again
- You get another 6! Now on 14, roll again.
- You get a 2. Final total 16.

So it's pretty much like rolling two dice, but _can_ get really high.

Combat damage is: Your Total - Their Total.
Your Total is: Strength + Damage + DRN
Theirs is: Protection + DRN.

So in the case you describe, you'd expect an average of 5 damage, but there's a chance of getting 0 (if they roll better than you) and there's no upper limit to how much damage you can do if you're really lucky.
