These mobs cast a spell called "Spirit Barrier" on themselves when aggroed which can be interupted. While this buff is active, the mob has a 95% damage reduction. The buff only lasts 6 seconds, but 25% of the time the mob is hit, Spirit Barrier will refresh on the mob for another 6 seconds. If the buff is on the mob, stop attacking it until it expires after 6 seconds, and then the mob will die very fast.
