⚡ What Machine Mischief does
When you use the mutation machine with the Gremlin out, the odds of getting a rarer mutation go up by 10%. It does nothing else, so it's a pet to equip before a machine run and swap out afterwards.
The ability text mentions a 40% max, but the ability data caps it at 20%.
