The most treasured loot I've gotten so far from The Barrows is: * Torags Platebody * 2 Guthans Helms (sold for 3.35 mill gp each =)) * Veracs Helm * Veracs Brassard * Veracs Plateskirt * Karils Skirt. Not to mention all the half keys - at least 4. Most people pray Protection against melee attacks and thus don't have to hide and run like I do, they just activate prayer and let their character autoattack with a magic spell they have set. So these players spend a lot of prayer potions to finish off the brothers in the crypts.
When you enter one of the crypts (spade needed) your prayer will be drained by approximately 10+ every 10 seconds or so.
Without the sip of a prayer pot Barrows would be impossible to do except for those very high levelled accounts. My way of barrowing is very risky but it saves me expenses on prayer potions. I have a moderately high combat lvl with 70 defense, but I only mage and range at Barrows as I have quit training melee altogether. Here is a simple description of how I do the Barrow runs. I stock up with runes for entangle spells (79 magic required) and magic dart spells (55 slayer required). I don't use pray on the melee brothers at all - I simply search their tomb and instantly entangle the brother that emerges. Then I run off a couple of squares and attack with magic dart. The tangle spell holds my foe to the spot for 15 seconds, enough time to cast 4 magic darts. Before the tangle spell breaks I run behind the tomb and waits 5 seconds before I repeat with a new entangle. After a hold spell has been cast and worn off, your enemy will be immune to any hold spells for 5 seconds! Therefore it is important to keep your distance from physical contact with the melee brothers if your prayer is off - their "embraces" aren't exactly like the ones you get in momma's arms =p Finishing off the Melee brothers like I do is very risky. You must know how to hide behind the tombs the proper way. I use a technique that is similar to "side-stepping", two of the corners of each tomb give this possibility. Side stepping is used by high levels that fight close up with the brothers - when they need to eat and regroup they have positioned themselves at a corner of the chest such that when they just move a step off from their foe which will be stuck on the corner of the tomb. I keep getting questions and comments on why I don't use Melee Prayer like everyone else. My initial thought was to save on prayer pots so I started using ancient magick. Again without praying melee. With my high magic level I can use Ice barrage - it holds the enemy for 20 seconds and deals massive damage. Ancient Magick turns out to be is very expensive, so I would start with an Ice Barrage and then continue my attacks with Ice Bursts. I made profit anyway (guess I was lucky with my lootings) - but I'd rather use my blood runes for some proper pk'ing.
After some experiments and testing I decided to continue with Modern Magic instead, and haven't regretted since. The risk has increased, but it only makes it more entertaning. If I should die and loose my Ahrims mage outfit or Guthan helm - well I hope the finder will be happy =p. So far I have been lucky - yesterday I got Veracs Plateskirt! Now I only need Veracs Flail for a full Verac set. Aaaa! - the satisfaction of picking up free stuff! This happened on the same day as I got Veracs Skirt! I was in Dharoks tomb preparing to take him down - as always with butterflies in my stomach - killing Dharok without melee prayer on is VERY DANGEROUS (that guy can deal at least 58 damage in one hit when his health bar is close to zero). Suddenly I see a player getting massive blows to his character, it happens so quick that he has no chance to escape. And voila! On the ground is the remains of this poor player - and what riches he dropped! I picked up: Obsidian Shield, Black mystic top and bottom, 200+ rune arrows, Berserker helm, black ranger set and so on. My inventory was full of lobs and I unfortunately had to see some of the things this poor player dropped being picked up by others as I couldn't gobble up them lobbies fast enough.
With a newly "looted" obby shield and a fresh Verac Plateskirt in inventory I decided to teleport to closest bank and have a break from the game. No need to test my luck further =P Anyway - Dharok is still waiting for me at the Barrows.
