I don't have any now :( Do we really need to do runs and runs and runs, or there is a way to have knobs quickly?

every new account starts with 999 knobs, so most shop runners just make alt accounts every time they run out

you have to have your alt join a server with your main account (because you need rock bottom badge to get to legacy) then, make a 2 player hotel- elevator on your main, and have your alt join that elevator. finally, make sure you leave the elevator on your main before getting teleported so you don't have to wait 30 seconds in the elevator. check this timestamp of my most recent stream to see what i mean

Thank you iheart_oofs and retrozy! Now I don't need to play a lot to have knobs,let's go :)
