Hiya,

Because the rates in ED2 seem to be concerning a lot of players, specifically the ability mutator codices, I’m dumping some of the important drop rate info!

Astellarn

  • flurry codex (1/500 group | 1/200 Solo)
  • the lorebook with a base rate of (40/1000 group | 70/1000 solo | 1/10 storymode) increasing by 1/1000 for each killcount you have solo or group
  • if the above 2 fail then fallback on to onyx dust. (5 in group/5-25 solo)
  • In addition to the above these items will always drop
    • 5-10 of certed red blue or black dragonhide
  • 1 reinforced dragon bone

Verak Lith

  • fury codex (1/500 group | 1/200 Solo)
  • the lorebook with a base rate of (1/25 group | 7/100 solo | 1/10 storymode) increasing by 1/1000 for each killcount you have solo or group
  • if the above 2 fail then fallback on to onyx dust. (10 in group/10-30 solo)
  • in addition to the above always drop
    • 10-15 of certed royal dragonhide
    • 1 reinforced dragon bone

The Black Stone Dragon

  • barge codex (1/500 group | 1/200 Solo)
  • pet item (1/1500 group | 1/300 solo) regular thresholds
  • draconic energy
    • group: 3/10 chance for 1-20 energies
    • solo: guaranteed if no codex and no pet 4-110 energies
    • calculations for the exact amount are a bit more complicated. To simplify, it's weighted towards small amounts, with a set of increasingly rare and large drops. I can go into more detail here if desired.
  • if in group and the above 2 fail then fallback on to onyx dust. (10-30)
  • in addition to the above always drop:
    • 1 reinforced dragon bone
    • One of the following:
    • 50-75 hydrix bolt tips (1/25)
    • 50-75 onyx bolt tips (1/10)
    • 1 Perfect gemstone scales (1/10)
    • 10-20 uncut diamond ~(1/2)
    • 1-10 uncut dragonstone (3/10)
    • 1 uncut onyx (1/50)

In all 3 cases the codices are the highest priority roll, and getting one of the other uniques means that the roll specifically for the codex already failed. Rolling positive on the lorebook will not prevent the codex roll.

If the lorebook / pet have been unlocked their base rate gets absorbed by the next item in line

All 3 bosses will also roll on a common table which is shared between them. The shared table includes some of the regular drops that appear across the dungeon, relics, gold, etc. This is also where the lucky charm rolls, and something on the charm table will replace the common drop.

Lucky Charm Table

  • Chance to trigger varies based on the enemy
    • boss 1/25
    • other 1/50
  • Drops
    • 1x lucky dragonkin coin (1/50,000)
    • 1x draconic energy (1/200)
    • 1x glaiven wing tip (1/33)
    • 1x draconic visage (11/200)
    • 1x dragonfire ash (4/25)
    • 1x elite clue (1/10)
    • 10-15x Onyx Dust (11/50)
    • 1-5 Onyx Dust (43/100)

What's the rationale behind having such low drop rates for the codices?

we felt like the awesome pogchamp drop moments were missing in ED1 because of the fractional nature of the t92 materials and onyx dust, so kept those and added the rare codices on top for the awesome factor.

We worked with the combat council who got some inspiration from players for the abilities to find a an ability mutator per boss that was desirable, but all melee.

Out of curiosity, when the one codex had a bugged drop rate, what was it? 1/50 group 1/20 solo?

yeah

I talked to u/shaunyowns about maybe dropping this info on the drop rates page in a more official manner some time soon. I wrote this up right now because I noticed that concern about the codices was coming up often here.

Thanks


So the 750 dry guy has had 2250 rolls at a 1/200 drop rate. Using Binomial Probability that leads to 1/79,080 which while its a rare occurence, it isn't astronomically rare.

EDIT: Where are mini-bosses classified for Lucky Charms Proc Rate (1/25 or 1/50)?


Sidebar, can we get this for Solak too, would be considerably simpler and its been over 4 months

Minibosses have the same proc rate for lucky charms as regular bosses 1/25

TIL 0.0013% isn't rare. Good to know.

just a bit rarer than the lucky dragonkin coin from a lucky charm, but that's happened already. This is the problem with probabilities, they do not blend well with human psychology.

It's definitely human psychology and not the fact you've already messed up the drop rates once prior on this exact piece of content. What was the thing that pointed out your content was broken? Oh yeah, human psychology and a decent sample size.

Yeah we screwed up, missed a zero, and when checking missed the fact that me missed a zero, but woah dude chill.

I'm not saying its not rare just trying to point out that rare occurrences do happen, especially with a large sample size like you say. And most of the time even the brain of a rational mathematician can make weird assumptions about probabilities and statistics.

There are lots of people who have run ED2 and going dry for 750 kills while rare isn't impossibly hard to fathom.

Serious question,.. do the mods say cert because of reading the code, or because they all play WoW and not RS primarily?

Code and they were called certs in RSC :)

Seems like that info might have been gathered by someone looking at the code before verak liths bug was fixed, that and story mode lore books are 1/10 base chance.

I think worthless isn't really the problem here as it takes ~100 hours on average per codex. To give some perspective, praesul codex is still keeping its price even though it's about 4 times more common than any of the ed2 codices. That's because it's very useful.

We're currently seeing this with mutated barge, its usefulness alone will keep its price even if you increase the droprate.

With dungeon clear times of 30 mins It's about ~33.3 hours on average for any codex, there are 3 of them and they are all rolled separately.

Another part of human psychology aside from a bias from drop rates due to anecdotal evidence, is that of anecdotal evidence holding more weight in the mind when it has been proven that Jagex can and have been wrong with their own suggested drop rates.

For instance, a 1/80k chance for something to occur, or Jagex just missing a few zero's in their code? To the general player, its more likely that Jagex screw something up, which they do often (just look at todays update full with bugs and complaints), than for somebody to go evilly dry on content that takes much longer to do.

I'm not going to get drawn further into an argument that's just going to circle itself, I'm sorry that we screwed up and sorry that you cant trust what I say today. :(
