Full matchup plan
Mid game · Walkers
Use Plot Armor on the teammate Rat King is shooting after rats attach to them. Place Captivating Read in front of him if he follows them toward cover.
Late game · Patron
Send Rallying Charge through your teammates and the enemies gathered around the banner. Aim from farther back when you can; the knights heal and damage more as they travel.
