How to Get a Black Dragon on Dragonkind
The rarest den in the Empyrean, and the single most-asked question since the site launched. The fandom has an answer — and it might just be your phone's battery.
Enter the Threshing Valley with your phone at 76–90% battery. That's the mechanic players reverse-engineered in the first days after dragonkind.com launched — and it's been reproduced widely enough that it's now considered the community-confirmed method.
◆ Why everyone wants the black dragon
In The Empyrean series, black is the rarest, smartest and most dangerous dragon den. No black dragon had been born in a century before the story begins, and only two are known today: Tairn, bonded to Violet Sorrengail, and Codagh, bonded to General Melgren. Bonding a black dragon is an extraordinary event that sends ripples through the entire war college.
So when players started posting black-dragon "assignments" from the dragonkind.com experience, everyone wanted in. It's the den with the most prestige — and, in the game, apparently the one with the most specific (and quirkiest) requirement.
Part of the appeal is simple scarcity. In the books, black is the smallest den in the whole of dragonkind: exactly two black dragons are known, and the approach lore teaches riders that black dragons are the most discerning of all — the ones least likely to bond anyone at all. Landing a black match in the game is the closest most fans will ever get to being Violet Sorrengail, and everyone wants a turn.
◆ The battery trick, step by step
The method, as the community has pieced it together:
- Check your battery. The community-confirmed sweet spot is 76–90% remaining charge.
- If you're outside the window, adjust. Too high? Play a quick game or scroll for a few minutes. Too low? Plug in and wait — or use your laptop's charge. (Note: most reports are from phones, which is what the mechanic seems to key on.)
- Enter the Threshing Valley at the right charge. Go through the normal flow — email, verification code, enter the Rider's Quadrant — with your battery sitting in the 76–90% band.
- Complete your Threshing run. Make your approach choices as you normally would.
- Collect your black dragon. Players matching the battery window report a black dragon as their assigned bond.
That's it. No special account, no hidden quest line, no paying anything — just your phone's charge level at the moment you enter.
Nobody outside Yarros Ink knows. The window is a pattern players noticed and then reproduced across hundreds of runs — reverse-engineering, not an official leak. Treat the numbers as a strong working range while the community keeps probing the edges.
◆ What's confirmed and what's still theory
| Claim | Status | Note |
|---|---|---|
| Battery 76–90% → black dragon | Community-confirmed | Reproduced across many player reports in the first days; no official confirmation from Yarros Ink. |
| Window is exactly 76–90% | Reported | Players are still probing the exact bounds — treat it as a strong working window rather than a law of physics. |
| Only works on mobile | Unclear | Most reports are from phones; desktop behavior is still being tested. |
| Approach choices also matter | Reported | Some players report that approach choices influence the den offered even within the battery window. |
| Replaying can change the result | Reported | Multiple players report different outcomes across runs at the same charge — a sign the window isn't the only variable. |
| Charge is checked at Valley entry | Reported | The level that matters appears to be the one when you enter the Valley, not when you reach the result card. |
Bottom line: the battery trick is the strongest lead we have, and it's easy to test — worst case, you replay and get another den. It costs nothing.
◆ Extra tips for the rarest match
- Time it. Don't enter the Valley, then sit on the result screen for twenty minutes before finishing — the battery that mattered was your level at entry.
- Use the approach protocols. Fans believe the book's approach rules carry into the game (greens want humility, reds hate eye contact), and black dragons are the most discerning den of all — so pair the battery window with a clean approach run. Full breakdown in the dragon colors guide.
- Replay freely. There's no penalty for another run, and players report the experience changes each time — your second black dragon is as easy to chase as your first.
- Help map the bounds. If you land a black dragon outside 76–90%, post it. If you try 76–90% and get something else, post that too — the community is actively crowdsourcing the mechanics, and edge-case data is the most useful kind.
- Share proof. Screenshot your assignment card and post it — every data point helps players confirm (or correct) the window.
◆ The black dragon in Fourth Wing lore
If you land a black dragon and want the full context, here's what it means in the story:
- Tairn (full name Tairneanach) — a black Morningstartail, over a century old, from the cunning Dubhmadinn line, son of Murtcuideam and Fiaclanfuil. He's bonded to Violet, the second-largest dragon on the continent, mated to the blue Sgaeyl, and the most respected dragon in the Vale — the reason black became the den every cadet secretly dreams about.
- Codagh — a black Swordtail, bonded to General Melgren. He's the only dragon in active service larger than Tairn, and Melgren's signet lets him foresee the outcome of battles — a pairing that says everything about how the Empyrean and the war college weigh a black bond.
- Black dragons are the most discerning of all riders' choices — bonding one is the kind of thing that makes the whole war college take notice, which is exactly why the game's black dragon is the match everyone is chasing.

◆ Frequently asked questions
Is the battery trick real?
It's the strongest community-confirmed mechanic so far: many players report a black dragon when entering at 76–90% battery. It hasn't been officially confirmed, so treat it as a very reliable trick rather than a guarantee.
Does it work on desktop?
Most confirmed reports are from phones. Desktop behavior is still being tested by players.
Can I replay to try again?
Yes — replaying is free and supported, and many players are rerunning the Valley to chase specific dens.
Which black dragons are in the series?
Two: Tairn (bonded to Violet) and Codagh (bonded to General Melgren). See the dragon database for both.
Will this get patched?
Unknown. Live experiences like this get tweaked, so if you want a black dragon, the window is open now.
Why are black dragons so rare in the books?
Only two are known in the whole series: Tairn, bonded to Violet, and Codagh, bonded to General Melgren. The den is the most discerning in dragonkind, and the books treat a black bond as an extraordinary event.
Do the approach protocols matter for a black dragon match?
Players believe the book's approach rules carry into the game, so pairing a clean approach with the battery window is the community's current best practice — though the exact mapping is still unofficial.
Has Yarros Ink officially confirmed the battery mechanic?
No. It's community reverse-engineered and widely reproduced, but not officially confirmed. The author has confirmed hidden easter eggs on the site, but not the battery trigger itself.
