See the additional post at the end of the thread for observations.Let me start by saying that I went into these runs with the full intent of recording every piece of data I could. I tracked the usage of all Pot’s, Food, Arrows, Runes and Gold. I also tracked which Brother I killed in the tunnel on each run, where the tunnel showed up each run, total kill count on each run and, once I figured out that the types of monsters killed in the tunnels influenced your Rune drops, I started tracking those as well. So with that out of the way, lets look at some data. Where I say total kills, it is exactly that, total kills which includes the Brothers themselves.
Runs 1-100 On these first 100 runs, I killed all brothers and then got my Kill count up. A few of these runs had only the 6 Brother kills, some had as many as 15 kills but not more than that.
So here are the drops from the chest for runs 1-100

Dragon Medium – 947
Runs 1001-1100. On this series of runs I went in with the intent of having a kill count of 10 on every run. This was because I needed more runs at 10 KC to continue to develop my Database.

Dragon Medium – 0
Runs 1201-1300. I could see I was way behind on my Chaos drops which I needed to get the Onyx gem to make into Furies so I droped my KC low because I know that Chaos drops better in the 6-8 KC range. I went with a KC of 7 for this next series.

Dragon Medium – 0
Runs 1301-1400. Again staying with the low KC, I went with 8 as I also wanted to see what was happening with Blood Runes and Bolt Racks. It became apparent with hundreds of runs now at 6 and 7 KC that Blood Runes and Bolt Racks do not drop for those KC’s. I wanted to see what a hundred runs of 8 KC would produce, as well as continue to generate Chaos Runes.

That’s 118 items in 1400 runs. That’s a Good drop about every 11.8 runs. Although, I think a more realistic average is 12-14 runs per item since that last series of runs tweaked the numbers a bit
For more observations on these last 100 runs, see my newest post at the end of the thread this date – Nov 20
Return to original post Dated March 23 2006 
Some final observations.
As I was compiling these numbers, I noticed several things right off.
First, is the kill count. If you look you’ll notice that as a general rule, the smaller the kill count, the
more Minds and Chaos Runes you get, but at the same time you get
fewer Deaths, Bloods and Bolt Racks.
As a matter of fact, if you look at runs 201-300 you notice something very startling. On these runs I only killed the 6 brothers and had 0 other kills. As a result –
0 Blood Runes and 0 Bolt Racks. At the same time, I got more Gold by far on this run than any other. That indicates that there is a formula at work behind the scenes. How the formula works would be interesting to know.
If you want Bolt racks, get the higher kill counts. With 600 kills I had 0 Bolt Racks, 900 kills was 210 Bolt Racks. 1365 kills was 2986 Bolt racks and then 1489 kills equaled 3354 Bolt Racks. It’s easy to see this increase in Racks as the kills go up.
If you use Magic Dart you should remember thati if you are running low on Mind Runes you need to make a few runs with a low kill count, this should start increasing the amount of Minds you are getting from the chest. By the same token, if you are running low on Death Runes, you want to increase your kill count for a few runs to increase the amount of Death’s you are getting from the chest.
The only magic I use is Magic dart and since I started this I have never had to buy any Runes to continue using it. My runs are keeping me completely supplied.
If you are using Ancient magic, and are attacking with Blood based spells, you need to get you kill count at 14 or higher, this will get you more Blood Runes in the chest.
Second, lets talk Brother drops in relation to kills.
I think it is random, but I could be wrong. Lets looks at the runs and the average kills vs. drops
Set 1***001-100 --- 10 kills average – 8 Brother Drops
Set 2***101-200 --- 14 kills per run – 8 Brother Drops (9 if you count the Drag Med)
Set 3***201-300 --- 6 kills per run – 2 Brother Drops
Set 4***301-400 --- 9 kills per run – 7 Brother Drops
Set 5***401-500 --- 15 kills average – 5 Brother Drops (6 if you count the Drag Med)
Set 6***501-600 --- 14 kills average – 9 Brother Drops
So again, Set 3 was just the 6 Brothers on each run and nothing else and 2 Drops. The least kills and the fewest drops. But because I have only this one set of 100, I would not go so far as to say that this is a true indication. Although I will point out that the runs before and after went back to what I consider a normal drop rate of about 1 drop in every 13 runs.
Just my opinion, but these numbers would suggest that a kill count of 10-14 will get you your best return on your investment.
As I mentioned at the top, I have also noticed that what creatures I kill can drive me toward certain runes in the chest.
Listed below are chest drop
averages by creature. These numbers are based on 15 runs of only that particular creature. All of these were done on kill counts of 9 (So 3 of the particular creature and the 6 brothers on each run)
Bloodworm – 298M – 88D – 135B – 21C – 122G – 0BR
Crypt Rat – 246M – 75D – 164B – 24C – 1084G – 0BR
Giant Crypt Rat – 189M – 81D – 162B - 0C – 1063G – 0BR
Crypt Spider – 74M – 98D – 162B – 39C – 1454G – 0BR
Giant Crypt Spider – 405M – 53D – 250B – 39C – 483G – 0BR
Skeleton – 291M – 70D – 115B – 40C – 1144G – 3BR
Skeleton with Shield – 417M – 86D – 109B – 33C – 1101G – 6BR
So, based on this data
If you want Mind Runes – kill the Skeletons with shields or Giant Crypt Spiders
For Death Runes – Crypt Spiders or Bloodworms
For Blood Runes – Giant Crypt Spider is your best choice
For Chaos Runes – Skeletons, Crypt Spiders or Giant Crypt Spiders
For Gold – have your head examined, this is not the place to be if your just after gold
For Bolt Racks – Skeletons with shields is by far the best return, followed by regular Skeletons
Remember this is only a 15 run sample of each creature.
I had a lot of fun doing these 600 runs, I had been concentrating on getting to slayer 85 and was burnt out on that so went and did the Barrows for a while. I feel refreshed and will be making another run at level 85 slayer, (only 1 and a half levels to go). Once I get 85, (and snag a whip or 2 of course

), I will return to the Barrows to finish up my little study.
My next set of runs will be exploring higher kill counts, I am going to do 100 runs at 18 kills, then 21 kills then 24 kills. When I get to 1000 runs I shall post again the total results and any observations that I have had.
I hope this information can help any of you that are currently doing barrow runs, or give some confidence to those of you that would like to but don’t know what the rewards might be.
