As a fellow Barrower, I thought I should make a guide, telling ya'll how to barrow using anywhere from 0 doses, to 2 doses of prayer pot per trip, depending on the tunell you get! Let's get started...Shall we?
Starting out in Canfis, which is East of Varrock, Follow the path highlighted in Red to Barrows.
Follow this Path until you get to the "Barrows Mounds" which looks like this.
This is my inventory when I go. Make sure yours is similar.
And here's my stats. This picture is kinda old so add +1 mage lvl +1 Prayer, and +1 Attack lvl
You can switch out D skim for Whip, and Red Dragon Hide for Black as you wish.
This is my outfit when I go.
Slayer Dart is the best methoud here, and Fire Blast is the Second best. Good thing about slayer dart is that armor doesn't effect it.
Now the good stuff. Once you get to the "Barrows Mounds" Start off on Dharok, and use your prayer on him. Next, work your way to Karil. Pot using the Strength Pot, and Attack pot, wield your dds, and dig. Put the rest of your prayer on (protect from range) and dds him to death, then pull out D Skim, or Whip, and finish him off. If you have any remaining prayer, go to Ahrim, and either range him, or Meele him. Whatever you do, wear dragonhide, and you don't have to pray if you don't have prayer. Just eat when needed.
From Ahrim, I go to Torag which is the easiest of them all. Just walk in, search and Mage him. Prayer is not needed here if you have Torags because Torag isin't that strong, and Torags armor is Awesome lol
Once you have killed Torag, work your way to Guthan, and repeat the same process as Torag. Don't worry about prayer because your armor will Protect you well.
Now finally Verac. He can either be mean, or nice. I don't pray on him, just take the hits and eat when needed. He isin't that bad. Just watch your HP.
Now, you do know there will be one where you are told to go into a underground tunell. Save this part for last. If you get Dharok, or Karil Tunell, well be prepared to use a couple doses of P pot. Once you have killed your foe, Kill one of each monster in there. People say "oo kill a lot of rats to get ur kc up" No, Don't. Kill 1 of each thing because each thing has a chance of dropping the item in the chest. You don't get D meds from barrows brothers. You get them from Skeletons or something so kill one of each monster.
Here is a map of the Underground Tunell
Thanks to

Your goal is to get to the center and search the chest, but in order to do that, you have to solve a riddle. If you can't get in on one side, try one of the others until you get one of the riddles. Simply solve it, and your in. You should have a Kill Count before you search the chest. If you have 11 Kill Count, Search it, claim your reward, and Teleport out. Don't be dissapointed if you don't get any barrows armor. It is not rare, nor common, just a matter of "luck basically"

Ring of wealth does NOT Help here.
Here are the rewards you may find when you search the chest.They are (from left to right) Ahrim, Dharok, Guthan, Karil, Torag, and Verac.
Thanks for viewing my Barrows Guide, and I wish you best of luck in your Barrowing!
