Right now I have a situation with a Doppleganger has infiltrated a small section of the group. It is passing itself off with the intentions of appearing to be someone important to one person and keeping that person alive so it can keep taking surface thoughts.
The question, I'd rather not have to roll Deception anytime something comes up or to tip my hand a bit if there is an Insight check. I know we have Passive Perception, but I was wondering if the creature could have Passive Deception as well?
