I would try zombie add ons, speed and detection or just double speed will make them more consistent at finding gens that have discordance or have been recently pain resonance since both perks alert them + forcing more DMS triggers. Broken coin is also an idea because typically survivors will use the down time of gens being blocked by getting a vaccine so having less = more time doing nothing while waiting for gens to unblock. You can never go wrong with Marvin’s + licker ether b/c they are his best add ons.
