As for armour and weapons at OSRS gold the level I'd recommend something true and hard hitting (use a whip and you'll only be a waste of space for your team - you would never strike ). Maybe this: Bandos Godsword (Use the Specific Attack to lower Defence). Helm of Neitiznot. Amulet of Fury (or even Glory in case you can't afford this ). Woodcutting Skillcape. Black Dragonhide Body. Dragon Boots or Climbing Boots (If you need to walk there - make sure these are the 75K ones, then they provide a +2 Strength Bonus). Great luck, you have got a great deal of training to do.
I say minimal for staff is 80 assault, 75 def,75 str, 52 summon,60 pray, 75 magic for magic def - Those are not minimum stats. Minimum is to be 85/85/85 using 70 prayer and 80 magical and maybe a fruitbat. As soon as I place the stats you indicated in zybez's combat skill calc it was 96cb. 115cb is the minimum and most teams would request the 115 to possess chaotics.
A fantastic def againest rrange armour (such as torag) -Nez helm, D'hide shirt and torags thighs is fine. Superior wepons such as ags or bgs+ claws or sgs or twisted rapir/maul - Agree. Sharks or food with superb pots - Rocktails would be best, and in the event that it's possible, extremes/ovls. On scape-xp calc it says it is going to be about 102 particularly I have stats close to this and I'm at 106 or 105 I do not really remeber. U need to go into the hp lvl tho and many teams will take 100+
Torag is much better. I said sharks or better u do not need to have stone tails and this is the same for super pots u don't have to get the lvl to make extremes or ovls. Off topic: I am not wanting to be rude or anything but the individual who has the article up the post u replayed on said the same thing like me but u did not replay on him really need to buy RS gold stop this cause that the ss vs. Whip topic were shut. And u know what is I am talking about...
