Randoms RuneScape gold also provides you the chance to meet lots of new people and make friends with all the individuals who are good at dung and you get on well with. After a time, you need to have enough friends who train dung which you may get together a team fairly easily, often with 1 or 2 randoms, sometimes with none. As for me, I do dung with friends a great deal, but I prefer to use randoms too as I can be sure there will always (or nearly always) be randoms online. This usually means I don't need to program my training around other men and women.

I would recommend getting 70 assault, strength, defence, range and mage before attempting barrows. You don't need that, only 70 mage and 50 triumphed to get a MSB or merely mithril bolts in Zanik's C'bow. It is good for me. Although I have better stats now. Should you do that though you'll want a canifis portal on your home which will require completion of DT (or it'll require slgihtly more time to get there, however, whatever).

You don't need to do DT, but it is an enjoyable pursuit and you're going to want it done sooner or later, and doing it now would be helpful. While you do not need then, 70 att,def,str,array and mage would help considerably. Magic dart is a great one...

You really, really, really don't need them. Barrows runs work fine without them. I am sure that 70 defence might help a little, but if you're utilizing ice magics, then you never need to melee anyway. Whatsoever. Karil gets ruined by magical and ahrim is just a bit slow to stove.

Ironically I do not normally do more than 1 run a time, but that is because I can't escape from the maze. (This was before I got a number of the levels you describe). I know I could do 2 or even 3 runs at a stretch. 70 defence is quite very cheap OSRS gold very helpful with blitz into sally, which can be one of the greatest methods(if you don't have access to turm/chaotics etc etc). Strike and strength speed up ahrim, however isn't essential and 70 mage is a minimal, 82 is better.
