I once had an old half-broken F150 that wouldn't die. The solenoid kept going out on me, so I'd jump-start it by shorting out the unit with a big ole' screwdriver. Sometimes instead of starting the engine would freeze up and refuse to turn over and I'd have to crawl under it and, reversing my grip on the screwdriver, use the handle to bang away at specific parts of the undercarriage to free the frozen components. The steering wheel was a little loosy-goosy, so I kept a spare ViseGrip in the glovebox - if the wheel ever fell off, I could clamp onto the exposed shaft and shove the screwdriver into the loop at the end of the ViseGrip, driving home with the screwdriver handle in hand, something like forklift-style steering. I kept that screwdriver squirreled away in a dry part of the truck's bed, so if I ever locked my keys in the car I could smash the window easy-peasy.
Sprinting Owl's stuff reminds me of my old screwdriver. Tight packages with just a billion little mechanics, inspirational bits, microsystems and hacks that can keep your TTRPG endeavors running, interesting, and vaguely threatening. I've bought a bunch of the items included in this bundle separately already, and it's still a steal for me at $13. It's probably something you should buy too.
