I'm about to start running a new campaign and one of my players cheats. A lot.
I'd like to stop him doing this, it annoys me when I'm trying to run a game... I like to let the dice fall where they will, but it's rather difficult with this sort of shenanagins going on.
Has anyone got any (sensible) suggestions? Dealt with this before?
It's not Morrus, is it?
(this is assuming you're the same Al I'm thinking of)
Seriously, The best alternative as I see it is to have a personal chat with him - not with the whole group, because it may seem too much like some kind of weird intervention. Just discuss that you've seen him messing with his rolls, and it's getting to the point where it's getting kind of obvious to the whole group. Don't use the word "cheating" as that is a harsh word and you don't want to lay down the law just yet. Just use "messing with", "spoofing", "fibbing", or whatever works for you. Just lay it on the line that it's no fair for the other players, and that you want all of you to have fun. See if you can get him to agree that, if he gives you as DM a fair shake, you'll give him fair treatment. Be as friendly as possible, because you're two friends talking about a disagreement at this point, not two adversaries.
If he runs from it or hides it, then you and the rest of the group have to decide one of two courses: either put up with it, or lay down the law with him. If you lay down the law, you simply have to tell him that his messing with his rolls is no fun for anyone, and he needs to stop. He'll need to roll with at least one witness, or you'll have to start rolling for him. It he can't accept that, then he won't be invited back.
It depends on whether or not he's worth keeping. The above assumes he's VERY worth keeping, as implied in your post.
Please note that my suggestions are based on my own personal experience, and implies no guarantee - in fact, my suggestions may be void where prohibited by law.
Good luck.
