If you've never done it before it's all about basically not getting overwhelmed, limit yourself to one action per prayer. For example - 1) Range TzTokJad 2) if you need prayer - 1 prayer dose, focus on switching prayers again 3) healers come - attack one healer, back to focusing on prayer (be careful as you might wander into jads melee range so perhaps move to side of him to get all of them) 4) keep doing that until all healers are on you. 5) focus on killing jad. Sometimes there's complications you have all healers on you yet they continue to heal him, you may want to kill them all off at this point, but it's entirely up to you, take it in stages though ;)
