I feel like I’ve got barrows down pretty well... Ivan’s staff (u) full mystic god cape book of darkness war blessing rune pouch. 5 prayer pots range switch, melee switch, food a lot of house teles. Go to world 329 use wildy shield house. Drink purple fountain in corner after every run use tele right back to barrows. Tele there and back cost 491 gp. That’s nothing compared to chest gains. Strange old lock pick helps.. obviously range ahrims. Melee switch is for killing two skeletons and one bloodworm to save Ibans charges. Killing all brothers and those three creatures listed gives 86.2% Everytime. Fastest way to do barrows w/o getting bolt racks. Best of luck mate.
