You do not have to do DT, but it's an enjoyable pursuit and you're going to need it done sooner or afterwards, and doing this now would OSRS gold be useful. While you don't need afterward, 70 att,def,str,array and mage will help greatly. Barrows runs operate fine without them. I'm 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 magic and ahrim is simply a bit slow to range.
Admittedly I don't normally do more than 1 run a time, but that's because I can't get out of the maze. (This was before I obtained some of the levels you describe). I know I could do 2 or even 3 runs at a stretch. 70 defence is very very very very useful with blitz to sally, which is one of the greatest methods(in case you do not have access to turm/chaotics etc ). Strike and strength accelerate ahrim, however isn't essential and 70 mage is a minimal, 82 is better. Note: I need the exp therefore I change the helmet. I have not completed the freminik quests . Going to Runescape 3 gold modify the black boots to dragon boots after I get a few additional 100ks. Haven't done monkey madness. Im trying to get dragon defender btw... Any information will be cool.
