Hi,
I used "Prone" as a name in my example, which turned out to be a mistake. I didn't mean to refer to the rules. The problem is that a mod does not modify the skill level as it should, instead it modifies the dice roll result which gives the wrong end effect. The problem is the same for CoC6. CoC7 and BRP, it's to bad if the same solution cannot be used, as it would save some time.
