Sooo.... I have a solid player base with six regular players, have GM'd for a year and half playing a very long running adventure though in recent sessions the player group has been operating under a repetitive narrative. For over a year we have played under the EotE theme and over three months ago their time line and adventures have moved them into a full blown rebellion following the battle of Yavin. They joined the rebellion and, as a specialist unit, have been given missions such as breaking out important rebel assets from Imp held jails, going behind enemy lines on a rebelling planet and rescuing stranded engineers. From their very first mission they snatched the imperial uniforms and laminate armour and had them repaired so they don't look battle damaged.
On their second mission they put those clothes on and impersonated imperial officers and soldiers. Thought that was inventive and went along with it. Deception checks opposed by discipline which succeeded with the players rolls opened up opportunities and they had a successful mission. Now my issue is that they are repeating the same narrative on all missions. That is they are dressing up as imps and infiltrating wherever they go and whatever the mission is.
I am throwing rolls for deception though am getting beaten down and now they have procured forged documents and by RAW its a daunting perception check so odds are stacked against me. So what I am looking for is assistance on how to narratively make it challenging to carry out the ruse in places within the imperial structure where it shouldn't be so easy. What form of security protocols, for instance, would imps apply? Does an Imp suit show anything other than the officers rank? That is their unit number, surname, etc. Is there anything else apart from them walking around and deceiving ordinary minion troopers and the occasional rival and nemesis, which they fool every single time.
Now an option would be to take it up a notch and improve the discipline of the next nemesis they approach though I would be accused of purposefully stacking the deck against them. So I am looking for a rational narrative approach to show that its not that easy just breaking into every single facility, followed by the opposed roll.
The group always uses the mouth piece character of the group as his deception is awesome. One line of thought I am thinking is to have an imp challenge another member of the group. Approach them and, say reproach them for their tardy way of wearing their uniform or someone that knows of the unit the uniforms represent and starts asking how certain men he knows from that unit are faring. Then a deception roll with one of the other players with a not so good deception roll.
Thanking you in advance.
