Rune drop rate in 1.13c
Hi.
I'm looking for chances for every rune that can be dropped in patch 1.13c.
TreasureClassEx.txt is file that I don't understand perfectly so I cannot calculate precisious rune drop rates.
I need to calculate those chances for every monster or every area level.
I really cannot believe that to calculate those chances i need only TreasureClassEx.txt.
Example: how to calculate chance that Hell Bovine could drop a BER rune?
Thanks for advanced explanations.

Here is where to get info on how to calculate the drops.
I did manage to find this http://dropcalc.silospen.com/item.php
Although I'm not sure how accurate this is, if at all.

Re: Rune drop rate in 1.13c
Reference the file guide https://d2mods.info/index.php?ind=revie ... w&iden=368 and the Appendix to calculate the chance of a drop.
So looking at the Hell Bovine we see it has the treasureclass, Cow (H).
We look that up in treasureclassex and we see the drops (gold) and treasureclasses from the Cow (H) treasureclass.
No Drop- 100
gld- 19
Act 5 (H) Equip B- 19
Act 5 (H) Junk- 19
Act 5 (H) Good- 3
Here we calculate the drop chances as per the Appendix in the file guide.
SUM = 100+19+19+19+3 and so on.
Note that a treasureclass can only contain treasureclasses that are above it in the file.
Looking up the Act 5 (H) Good we see it has the treasureclasses
Jewelry C- 60
Chipped Gem- 4
Flawed Gem- 10
Normal Gem- 14
Flawless Gem- 28
Runes 17- 14
Again we calculate the drop chances as per the Appendix in the file guide.
Then finally we have the runes.
Runes 15
r29- 3
r30- 2 <-Ber Rune
Runes 14- 2941
Runes 16
r31- 3
r32- 2
Runes 15- 3957
Runes 17
r33- 1
Runes 16- 5170
So then we calculate the drop chances as per the Appendix in the file guide.
As in the treasureclassex file the Runes 17 treasureclass will down grade to Runes 16 and so forth.
We can see the chances of a Ber rune dropping is very low.
I leave the calculations as an exercise to the reader.
Also note these are numbers from my 1.10 files and the rune drops were a bit improved in later patches.

An offline version of that drop calculator is included with GoMule.Black_Eternity" wrote: I did manage to find this http://dropcalc.silospen.com/item.php

Same Author, and same question of accuracy applies.

Re: Rune drop rate in 1.13c
Cow "picks" = 1 so one cow can drop one item?
Sum of Hell Bovine probabilities: 100 + 19 + 19+ 19 + 3 = 160
Sum of Act 5 (H) Good: probabilities: 60 + 4 + 10 + 14 + 28 + 14 = 130
Sum of runes 17 pack: 1 + 5171 = 5172
Sum of runes 16 pack: 3 + 2 + 3957= 3962
Sum of runes 15 pack: 3 + 2 + 2941 = 2946
Game calculations when Hell Bovine dies at /players 1:
Chance to drop Act 5 (H) Good = (3/160) (chance to turn off magic find [misc drop])
Chance to drop runes 17 pack = (14/130)
Chance to drop runes 16 pack = (5170/5171)
Chance to drop runes 15 pack = (3957/3962)
Chance to drop r30(ber rune) = (2/2946)
Then:
Ber rune drop chance = (3/160) * (14/130) * (5170/5171) * (3957/3962) * (2/2946) = 0.00000137
0.00000137 = 0.000137% = 1:730000
So we need do about 2086 HC(Hell Cow) runs and spend about 200 hours to get Ber rune. Thank you Blizzard for this game.

Re: Rune drop rate in 1.13c
The calculator gives 1.13 a better chance..Hell Bovine - hellbovine (H) The Secret Cow Level 1:2915781
That chance is for every Cow killed. It could happen on the first kill of the first run or maybe never...
Gotta love the Game!

Re: Rune drop rate in 1.13c
"better chance". What do you mean?
Am I wrong with my calculations?

Like I said in my first post. Those numbers are from my 1.10 files.

Re: Rune drop rate in 1.13c
I looked into my 1.13c TreasureClassEx.txt and my numbers are the same like yours.
I'm 99% sure that my probabilities belong to 1.13c patch.
