@XxFellsingxX since he is sneaking, I'd say perception. Insight could work because at this point since you jabe learned to expect Arma to do this sort of thing.
Edit: I will say, usually I let players rp situations out together. There is no need for dice rolls unless you guys can't agree on how you want things to go down. If you want arma to be caught, you can forgo the rolls
Edit edit: once we determine who is going in first I will post, sorry for delays yall.
@XxFellsingxXI know the feeling, had a lot of family around recently too. Take your time.
Work is about to get incredibly busy for me. Horse races are about to start and I live in Kentucky. I work catering events so I will likely be dealing with a lot of rich people and might not want to post for a while.
