The way I do it with ancients is virtually free. I melee Karils first, kill him in about 5 or sometimes 10 pray points. Melee Ahrims, kill him in about 10 or so pray points. I switch to mage gear, finish off the rest of my pray points on Dharok using Ice Burst. When I kill him I am usually out of pray points or have a few left over. Then I kill Verac, Torag, and Guthan with Ice burst while hiding behind tomb. I only have to use a dose of pray pot if Kharil is my tunnel. I usually only use about 80 deaths and 160 chaos during a trip and I'd say about 80% of the time I get all of them back in the chest. Then I tele to lumby with a tele tablet, fill pray, tele to Canafis, repeat. Each trip takes about 5-10 minutes. And I have a lot better luck with Ancients than with slayer dart, ive gotten 17 items at Barrows with Ancients and 3 of them were Guthan Warspears. :D Mr Blasty33
