For a side quest we got job from a shady figure my character and two other player characters went to break into a smithy's home/workplace.
When we were in there our brute, low intelligence, tabaxi ranger took some new armor for himself dropping his current armor on the ground. When making our way out I disguised myself but rolled a horrible performance check when trying to convince two guards I was just strolling around with a box full of mushrooms.
We ended up killing the guards and fleeing. However the guards saw the faces of my companions and one of them left his personal possessions at the crime scene. Now, in a few in-game days we will be fighting in a public tournament and we will want to prevent being arrested on the spot.
Is there a way to make the guards unable to track us by our personal possessions and disguise my companions for a few days?
Extra information: we are level 4, the guards would have access to mages from a large institute I wouldn't really know what kind of magic they would have access to but the DM hinted at a spell to track a PC by his/her possessions. We are a rather magic deprived group with only one mage, two rangers, a rogue, and a barbarian. We do not have access to any relevant utility magic. The armor left was normal heavy armor and we did not kill all the guards we killed two and were able to use zephyr strike to dodge away from the other 10 that were called in by a horn.
