Mass Combat: Failing Strategy Roll with a bigger Margin of Success than the Winner

[hal]

By definition, any roll that is 10 higher than your skill/attribute being rolled against is deemed to be a crit failure. An 18 is always a crit failure, so you may wish to equate the two in a quick contest. That is to say, a 17 becomes a normal failure if your skill is 17+, with an 18 being a miss by 10.

This is not stated as such in the rules, so take it for what it is worth.

One house rule that I use is that there are no crits in a contest. Keeps it simple as it were.
