You will need to pull the two mobs roughly 50+ meters apart so their effects do not overlap. Each mob will cast a curse on the person who is the farthest away from them. Position two members of your raid on either side of the named mobs so they are the furthest away. When the players get cursed they need to run to the opposite mob and touch them to remove the curse. Head back to your normal spot and wait for the curse to land again in roughly 30 to 45 seconds. Keep up with the healing and you complete this encounter.
