This infusion has an instability level of "Very High".
It didn't take you long to come to the conclusion that you hated all those times a creeper snuck up on you.
To that end, using the knowledge you have that creepers run away from cats, you have devised an amulet that by simply being carried on you makes all creepers run in fear of your presence. Not only that, but they'll be petrified to the point of not gathering enough stoke to explode. Great. It must be worn in your amulet slot to take effect.
