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)
