Barrows loot log

[Powerfrog]

Well it looks like I'll be doing a lot of barrows and not much else so I might as well record my loots.

 

Note that every chest will be 6 brothers dead and 8 mobs, as this is supposedly the best way.

 

2nd chest - Dharok's helm!

35th chest - Torag's hammers...

50th chest - Guthan's helm!!

[Powerfrog]

Not very exciting at the moment but when there's more data I'll have separate tables to list how often I get each item and some sums based on probability of item per chest etc... I will NOT be recording runes or bolts as they sadly just take too much effort to keep track of.

 

I'll use this part to tell you my current method (tips would be welcomed)

 

Start in Canifis bank.

Run to cellar behind pub, walk through shortcut, climb up the tree and run to the boat.

Cast "charge".

Kill the brothers in the following order: Verac, Torag, Karil, Guthan, Dharok, Ahrim.

Mage the first five with Flames of Zamorak, wearing full melee offensive armour. DDS + d scim on ahrims. Obviously skip any brothers that lead to the cavern and go back once 5 are dead.

Now kill 8 rats/worms as you make your way to the chest, the last brother usually appears as you open chest, kill him before looting.

Loot chest.

Teleport home - Pray at your altar, use the portal room to teleport back to canifis, run to the bank and resupply if necessary. (Otherwise save a few seconds and just go straight back to the cellar)

Final reserved spot, feel free to post.

Dh -> karil -> ahrim

 

Tank the rest without prayer.

 

Use no p pots this way unless dh tunnel and you can force spawn him into a safe spot.

I'm 42 defense 43 prayer so I really can't tank the melee guys and cant kill 3 without pots. I will do this for sure once I'm 70 defense 70 prayer.

 

In fact I think I'm just gonna train defense now, I don't even care much for zerk pking.

Do list your killcounts and rune/rack rewards.

Do list your killcounts and rune/rack rewards.

I list the ongoing chests looted with each item, I have currently looted 42 chests, but won't write it down unless I get an item. If next chest is an item, i will write 43rd chest - Ahrim's staff. It feels like a waste of time to update otherwise.

 

Killcount will always always be 14, 6 brothers dead 8 mobs dead. If I ever fail to do this I'll disregard that chest from the log.

 

Not going to list runes or racks. Too much effort. They're so common you could just record like 100 chests and get their probability down to a near science anyway.

Not sure how to embed.

 

EDIT: Embeds itself now. Mind = blown.

Video was with double runes. (And killcount unknown but in many screenies it's 20+)

 

Per chest after halving: 14.6 bolts, 25.6 bloods, 58 deaths, 101.8 chaos, 304.2 minds...

 

Counted 44 barrows items. So that's 1 item for every 22.72 chests. (Wow that's worse than I expected.)

tips would be welcome? Like, advice to improve your method or money for sharing your method?

I always enjoyed Barrows, maybe I'll join you in your quest for barrows greatness (and/or insanity) after 80 prayer! :P

[Powerfrog]

...Yeah I'm currently still training my defense, soon I'll have 70 and will actually do some more barrows (To make the money for piety!) :D

Advice! I really dislike people asking for "donations" or "tips".

[Powerfrog]

Hey so I've got 70 def and doing barrows... Looking at item prices and have to ask if it's worth bothering with ahrims at all.

 

Having lame melee stats VS ahrim means lots of prayer and or food used, not to mention time.

 

Does anyone know if like 5 brothers + 9 mobs has the same chance of getting a guthans item as 6 brothers? Or any glimpse on how it effects the chances?

[Saradomin_Mage]

Chances of any barrow item go up as you kill each brother, with six brothers giving you a higher chance of an item than say just one. You could avoid Ahrim and end off with 5 brothers killed but that'd give you less chances than if you killed all 6.

 

I don't think the monsters and brothers are interchangeable for KC, but I wouldn't know, and Mod Dean doesn't elaborate; however, the EoC interface that splits brothers and monster killcount suggests that they aren't.

 

I would have suggested ranging Ahrim but you've got like 44 ranged, so eh ...

[Ammako]

Chances of any barrow item go up as you kill each brother, with six brothers giving you a higher chance of an item than say just one. You could avoid Ahrim and end off with 5 brothers killed but that'd give you less chances than if you killed all 6.

If I understand your post right, you're saying that killing Ahrim would give an increased chance of obtaining Guthan's armour?

 

If that is the case, I don't think that's how it works.

Each barrows brother's items have their own slot (possibly more than one) in the chest's drop table. Killing that brother allows the chest to pick from that brother's equipment when you loot it.

 

Killing all six brothers increase your overall chances of getting a Barrows equipment piece because there is more equipment drop slots available. But you would have pretty much the same odds of getting, say, Dharok's helm (specifically) if you were to kill only Dharok than if you were killing all six brothers.

 

Now, it's true that killing all six brothers would increase the profits obtained from the chest, since it is better to obtain, in this case, an Ahrim's item over receiving nothing.

But the question is, does the increased profit from getting Ahrim's equipment make up for the extra time spent killing Ahrim?

 

 

tl;dr killing a barrows brother lets you obtain his equipment from the chest, and killing all six brothers gives a better chance of obtaining any barrows item since there is more to choose from. Chances for a specific item does not change.

[Saradomin_Mage]

Chances of obtaining any item flat out increase, so killing Ahrim would increase your chances of obtaining, for instance, Guthan's helm (in a way).

 

You basically have a chance of first receiving a barrow item, and if you score this chance, an item from the pool of available items is then selected.

 

For instance, you kill Ahrim and Guthan.

 

You get two chances of scoring a piece of equipment: once from Ahrim's roll, once from Guthan's roll.

If you succeed on Ahrim's roll, you can then obtain any piece of Ahrim's or Guthan's gear, since you killed them. This is how it's possible to receive two of one brother's pieces of gear in a single chest.

 

Edit: Notably, your chance of getting a successful roll for a barrows item increases as your brother KC goes up. If you kill only 1 brother, your chance of succeeding on your barrow item roll is approx 1/334, whereas if you kill all 7 (fixed in EoC), your chance of succeeding on the roll is increased to 1/44.

I'm more confused now than i was before asking. Mod dean seems to pull out the 450 - X digits out of nowhere with no explanation, i don't doubt their credibility but they're pretty unhelpful without context.

 

And 7 brothers = 1/44 chance? Huh? Runeshark have 880 chest log and they average 1/15.4. No idea how the mobs effect the chances though Runeshark themselves seem to have misconstrued(?) the same information as previously posted on this forum and think they need 8 total killcount (6 bros 2 mobs) instead of 14...

 

I really wish they'd just provide the code/formula, if they're giving out of context tips like this they might as well.

 

I still have no idea what the difference between 5 brothers and 6 is. Ahrims is currently so time and resource consuming it'd be worth a slight decrease in Guthans items just to get more chests/hour, emphasis on slight.

 

I've got a bad head.

[Ammako]

Jagex don't appear to be the kind of company that is willing to give away the specifics regarding their game mechanics, which is a shame really. Would make everybody's lives easier.

[Powerfrog]

Dean seems extremely active on the forums and that thread so I've asked myself :)

 

Here's hoping he answers.

 

 

For the time being I'm going back to killing 6 brothers and 8 mobs, hopefully add some stuff to the log.

[Saradomin_Mage]

Mod Dean has some 450 - X formula, where X is 116 for one brother and 406 for seven, so extrapolating from that you have roughly 357 for six. That's 1/93 chance of a barrows item for each of the brothers killed, so with six brothers you have 1-(92/93)^6 chance of a barrows item per chest (6.3%). This roughly matches RuneShark's result (1/15.4 = 6.4%).

 

 

If you continue to extrapolate, with five brothers you get 308 for X, so a 1/142 chance of an item per brother. You then have a 1-(141/142)^5 chance of a barrows item per chest (3.5%).

[iAnt]

My method uses 2 prayer doses max per run.

 

Karil > Ahrim > Dharok > Guthan > Torag > Verac (Kill in tunnel using safe spots and ladder spots)

 

Never use over 2 doses of p pot - saves a lot of cash!

[Powerfrog]

My method has changed entirely, here's what I do now. (still open to suggestions and will check out various methods)

 

Ahrim first, pray 15% atk and str (and protect mage), unload 4 dds specs into him then d scimmy for the kill. Usually takes 45 prayer points or less to take it down, can occasionally just spec him out immediately!

 

Dharoks next with prayer, then karils with prayer.

 

The remaining 3 are killed without using prayer, i usually go through a few lobsters.

 

And the biggest change is after I've looted chest i will remember where the ladder is and make my way back, getting 2 chests in 1 trip! A huge speed increase.

 

How do you guys handle the run energy problem getting there? I'm considering energy pots.
