Now before you read on, this is just a theory, this maybe just based on some extreme luck but still worth invstigating. Everyone thinks, that to get a good item at barrows, you need to kill all 6 brothers and open the chest as fast as possible. This theory maybe completley wrong, as jagex has not confirmed it in anyway (nor did they prove it wrong). One of my trips at barrows, my magic kept hitting 0s, and eventually i killed 5 brothers and torag was my hidden tunnel. I got my kill count to 9 before searching for torag, adn then i went to the chest (where torag would appear when i opened it), to make things longer, the chest door was very far from me and when i got there i got the puzzle WRONG!, so then the door moved to the opposite side of where i am, making things even longer. Finally when i got to chest and killed torag, i thought I wasnt going to get anything as this trip was my longest one yet. But guess what? I got guthan helm AND body in ONE chest! it was my first double item chest! (I also got over 100 bloods and deaths!). AND if this isnt enough evidence to investigate, here is another incedent that happened to my friend: He was doing his trips and it was taking him longer than usual because he was tired. When he got to the tunnel to get his 6th brother, he realized he was out of prayer pots, and no more food. He was also low on health and couldnt risk losing his stuff AGAIN (lol). So he teleported out with his ectophial, and restocked. He came back and finished his trip and what did he get? DHAROK LEGS AND AHRIM TOP!!! (ALSO some good runes, although i cant remeber how many.) --- So... does this mean the time factor has no effect, maybe the longer it takes you to do a trip the better items you get, or maybe this was just some very good luck? Either way more investigation is needed and I will investigate this when i go to barrows later.
