1) You kill the Lv 90's first, before every other monster (with the possible exception of lv 22 bats.) If you have a problem, turn on steel skin when the wave begins. 76 defence is grand, i did it with 77 defence. in fact i did it with a much lower ranged level than you (75), so you shouldnt have too much of a problem with them. Make sure you are using muggi's guide though, guthan's set makes it harder because you have to actually melee the guys (and having a lower prayer bonus, meaning your prayer will drain faster and you need to pot more often) 2) For mage attack, he pulls up his legs and holds them in the air for a while before letting them back down again. When jad pulls them up, you will also hear the sound of retribution prayer going off. Thats when you turn mage prayer on. If he pulls them up and slams them down immediate (as well as having no sound when he does that), its ranged attack. Put on your ranged prayer then.
