Enchantress concept art.
The Enchantress, Eirena, is one of the three Followers the player will encounter in Diablo III. She is a ranged magic wielder and crowd-controller, acting largely in a supporting role.
Her skills focus on disabling attackers (knocking them back, slowing them, or increasing the amount of damage they take), and improving your defence and attack rate.
The Enchantress is able to equip two-handed staves, two-handed swords, two-handed maces, two-handed axes, two rings, one amulet and an Enchantress-specific item.
