Consider: alchemizing gloves and some overwatch merch to make symmetra gloves, setting turrets around your house so you can sleep, and every moring u wake up with mad crazy grist to pick up
There’s speaker system in the house meant to play the “Welcome to my Reality” voice line every time an Imp goes in.
That being said, that’d not be that mad grist, Imps only provide so much. It’d keep your house clean from Imps though.
