⚡ Ability
Wiki passive: Machine Mischief: Increases your odds of rolling rarer mutations from the Pet Mutation Machine!
This is an always-on passive, so there is no cooldown to track. Like other pets, its stats scale with weight.
⚖️ How much does a Gremlin weigh?
There's no fixed weight for the species. Each Gremlin hatches at its own Age-1 weight, and every age adds one-eleventh of it:
So a Gremlin that hatched at 1.00 kg weighs 10 kg at age 100 and about 46.4 kg at age 500. Enter your own pet's kg and age in the pet KG calculator; for the XP each age costs, use the age calculator.
