Feat: Forensic Countermeasures

Your knowledge of deductive reasoning allows you to derail fellow investigators. Over the course of a minute, you can tamper with a single location (such as a small room) to either obscure evidence or add misleading evidence. If you add misleading evidence, you choose what incorrect details it implies. A creature can see through these countermeasures with a successful Recall Knowledge check against your Deception DC, and only if they actively look for tampering.
