#1 I pray on Dharok and Karil, and whatever leftover points I have I use on Guthan. I rarely eat on him. I don't pray on the other three, and I eat generally 3-5 monkfish - bear in mind I've got 64 mage, 70 defense, and rune plate+legs. #2 Since Ahrim has ZERO range defense, then you can easily range him, especially since you've got 70+ range. The bows preferred: magic shortbow, or Karil's crossbow. I'd suggest mithril or higher ammunition. #3 You've got 80 attack and strength, right? Melee Karil. I can easily melee him potted to 86 attack. If you seem to not be hitting enough, bring a (super) attack potion. Super isn't needed, unless you make them and have a surplus, or like to buy them. :P You should probably pray on Karil, until you get higher defense and better armor, and get more comfortable with Barrows. Oh, and use DDS specials, and then a whip on him. I usually get decent specs and get him poisoned. #4 I eat 7-10 monkfish on: 70 defense 64 magic 62 range 51 prayer Rune plate, legs, berserker, glory, unholy book, God cape, rune boots, air wave. I also never drink a prayer potion unless I get a Karil tunnel, or I run out of food somehow.
