Pete can take Barricade.
Good game, everybody go home, better luck next time Azathoth.
Now, letting monsters build up isn't always a good thing, especially in scenarios with Acolytes or ones that require backtracking. But the ability to just not have to deal with monsters at all for a single action and zero resources is incredibly powerful.
Other fun shenanigans: infinitely recursive Grievous Wounds mean you can whack an enemy once, play a tune to make them disengage and move away, and assuming they don't have hunter, just leave them to die. Or, bring a katana and some good shoes. Move into a location with an enemy, before they engage you test your shoes. Testing the shoes gives you a fast action window before drawing tokens where you can trigger the fast action attack from katana, which then gives an opening for grievous wound. The shoe test then resumes and you move out of the location before enemies can engage you. The anime potential is overwhelming.
Pete can go on the hunt to draw a harmless enemy, kill it for three bucks, and instantly bounce it to his hand for next round. Combine with the usual guardian clue suite for free clues.
And of course Makeshift Trap is basically made for him, except that the explosive upgrade doesn't work with his ability. Bah humbug. Still, poison + net + remote means your guitar can herd any number of enemies into an infinite deathtrap from which they can't escape. It's a very slow death, and his 0-4 limitation prevents you from also making it fast, but it does the job,
