Full matchup plan
Mid game · Walkers
Use Dust Devil to knock Rat King up when your teammates can shoot him. If he activates Royal Pestments afterward, move behind cover until it ends.
Late game · Patron
Remove attached rats with ground or air dashes before using Traveler. Their damage can cancel it before you leave; choose a destination near teammates and cover.
