So far as the 90's go, when they are alone (without a level 360 I mean) you should pray shield from range against them, but whenever there's a level 360 outside, you should always be OSRS gold shielding from mage no matter what else there is, rangers or maybe not. This becomes a problem from the 360-180-90-90 wave but if you brew up before then, you ought to do fine.
It could be that youre simply not using prayer efficiently, I tried the fight caves this evening, died at wave 58 but at that time I still had 4 brews and 9 restores. In addition, I have 70 pray, and lower defence and much lower ranged compared to you. Just make sure youre not using unnecessary temptations (I.E., no eagle eye before jad, no defensive prayers unless youre actually getting ripped up on the past couple of waves), and be certain that as soon as you've got a wave which has a 360 and a 180 in it, trap the 180 supporting the 360, just pray mage before the 360 is dead, then safespot the 180.
One last thing, ALWAYS MAKE SURE YOURE KILLING THE LEVEL 22 BAT THINGS FIRST! Even if you can find different things like a 360, or even a 180 or the 90's you should always, always, ALWAYS kill the bats first. They drain your prayer with every hit and even though they may not appear so dangerous they cost you a lot of money in the long run.
Is their anything I must change? And I have to learn more about the things I asked about whats better, thansk to anyone who replys and im not trianing any more levels... I am away to get a sacred rench ill replace one of the uper restores with it's this a fantastic idea?
I have been making my new pure and have some queries as it is my very first real p2p pure. 1. About just how much money would I shed alching ruby rings in fairytopia from 55-82? 55-70? 2. Seeing as I am 52 range 22 pray up to now, 38 cb, just how long should 38-55 slayer take if it is all I do training wise? 3. Does this stat place sound good for pking on my first pure? : 50 atk, 75 str, 85 rng, 82 mage, 26 beg (essentially range and Old School RuneScape Gold mage until I may have a maul opportunity k0). 4. How long does 70 Ability take from 52 in wildy class? 5. How long could 70-85 range shoot blue dragons? 6. How long does 53 thieving take? I'll have more questions ensured! But thanks for helping with the current ones so far!
