Agile Guardians are Undead located in the Apothecary's Cellar in the Blighted Village during Act One. They spawn out of the caskets within the Graverobber's Cavern, fighting alongside Robust Guardians. Befitting of their name, they are quite fast with their extra movement speed, with them focusing on reaching other caskets to free up more undead. This can become quite hazardous if the flaming trap of the magic mirror is unleashed as well.
