I'd really advise getting 70 attack, strength, defence, array and rs3 gold mage before trying barrows. You don't need that, just 70 mage and 50 ranged to get a MSB or just mithril bolts in Zanik's C'bow. It works for me. Although I have better stats now. OP: get DT performed for Ice burst, unless you have 55 slayer in which case I imagine you are able to use magic dart. Should you do that though you will need a canifis portal in your home which will require completion of DT (also it's going require slgihtly more time to get there, but, whatever).
You don't have to do DT, but it is a fun pursuit and you're going to need it done sooner or later, and doing it today would be helpful. While you don't need afterward, 70 att,def,str,range and mage would help considerably. Magic dart is a good one... No, seriously, I mean: the melee levels? Barrows runs work fine without them. I am positive that 70 defence may help a bit, but if you're using ice magics, then you never should melee anyway. At all. Karil gets ruined by magic and ahrim is just a little slow to stove.
Admittedly I do not normally do more than 1 run a time, but that's because I can not escape from the maze. (This was before I obtained some of the levels you describe). I know I could do two or even 3 runs at a stretch. 70 defence is very very very very helpful with blitz to sally, which can be one of the best methods(in case you do not have access to turm/chaotics etc etc). Attack and strength accelerate ahrim, however is not essential and 70 mage is a minimal, 82 is better.
And this is my current set up: Sacred Clay Helm, Granite body, Dragon Platelegs, Amulet of Glory, Ring of riches, Obsidian cape, Dragon longsword, obsidian sheild/Mithril guardian. I have around 1 mil to update my armour/ wep. Note: I want the exp therefore I change the helmet. I have not done the freminik quests either. Going to change the black boots to dragon boots after I get a few extra 100ks. Have not done monkey madness. Im hoping to become dragon defender btw... Any information will be cool.
It did lol, I got 20k-30k exp 2 afternoon in str, which is way more than my ordinary... I never train to get substantially over one hour in a strech, as I like making frnds and having fun more than skills. And neit doesn't work for my , like I stated in 1st post, I have not done the fremmy quests, which is a repuirement. I can not manage to keep buying degradable armour, so I wana know if its degrade too. And buy OSRS gold tyvvm for submitting.
