For weapon RuneScape 2107 gold either do magical shortbow or rune crossbow with whatever bolts/arrows you prefer. If you've done heritage of seergaze though and want the fastest xp have a cannon and prayer equipment to the tunnels near the bloodstream altar. Locate the area with the mutated ones, pray melee, start cannon, make sure auto retaliate is on and proceed. Prices a fair amount of cash to do so but it's easily among the fastet task you will receive. And seeing as they have a large amount of hitpoints it is also one of the most appropriate for xp.
If you go to w67 you can typically get into teams as soon as you have 100-105. I haven't played for like 3 months so a good deal of this has probably changed. W67 is generally dominated by s/l now... Make some friends that are good dungers; together with the people I dung with that I will average sub 15 minute warps even with 1-2 randoms from w67 - you might have to combine someone like 3b0 to start off with, but something such as DGS with enormous commitment not to actually get much from it - you're spending around an hour to get together an application to a clan that makes you bind primal baxes!
Yes, I applied based on multiple buddies who used dgs into 100+ who stated it's the very best and 3bo is crap, for what that's worth, I have only done 1-2 flooring with them ever, but applied since I plan on dging soon. Even if 3bo does have been better, dgs is the only decent alternative to 105/110+ anyways. From what I am told, 3bo became overun with 117 crap dgers who do not even know more than the basics of dung and they are there, I'm sure there are certainly good keyers and teams in 3bo nevertheless however, so thats kinda why I reccomended exactly what I did, to utilize both.
I don't know how a lot of those store runs you actually need to perform too, buying out every shop would boost cheap OSRS gold overall gain, but some take too much time to get to to make the profit worthwhile, afaik, bstaves/broads/maybe culm's torso are the essentials, everything else is more discretionary.
