Bring 1k broads. You'll only use 500-700. Change the helm from Veracs or neitiznot. Legs can be prossy or verac. Boots to either rune or RS gold dragon. As far as the strategy goes, getting the 180's with the 360's or 45's is one of the top priorities.
The other is the one that is killing the 90's. 360's and 45's should be the last ones. Try to eliminate the 22's as soon as possible cause they draw out prayer. Hardest waves are 53-60, which is when the 360/180/90 trio comes out. The trick is to first find the 90 and go behind it, take it down, and run around the 360 or to either the dragon/italy rock, and then trap the 180 whilst killing the 360.
Once you get to jad, brew/sup up to full stats , and also a range pot, and switch on the range prayer. If the attacker hits you the first thing you need to do is to determine which attack that he's going to do next, and you should only brew/sup/range in between prayer switches. For healers, it is recommended that you are praying the eagle's eye/steel's skin and buy OSRS gold either kill them or tank them one by one. The former is less difficult as far as time wise but could be more hazardous. Best of luck.
