Engineers have several new toys coming in Dragonflight, one of which is the S.A.V.I.O.R., a friendly mechanical construct which will offer moral support as your companions fall around you! Like the Failure Detection Pylon, the SAVIOR will resurrect party and raid members after a wipe. Between this and the Arclight Vital Correctors, who even needs a healer?!
Like the Failure Detection Pylon before it, the applications of the S.A.V.I.O.R. are near limitless!
