Dragon KeysLevels 10, 15, 20, 25, 30

A Dragon Key is what opens a rare crypt, which is where the gems come from.
The same five steps as the rare crypts they open, level for level.
What is behind an Elven citadel’s walls, and what people take to it. What to bring and in what order comes from a clan’s own chat, so that half is one set of players’ practice and not a rule.
A citadel is not fought by bringing the classes that counter those ten. It is fought by arranging strengths, because what each of your stacks attacks follows from how strong it is and how much health its target has.
How the striking sequence is worked out →
The ten that garrison an Elven citadel. Health is three times strength in every one of them, walls included.










What is actually inside each one. The walls come first because a march without catapults does not get past them.
| Citadel | Citadel Walls | Dwarf | Elven Archer | Druid | Centaur | Pegasus Rider | Bear | Unicorn Rider | Ent | Life Dragon | Total health |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 10 | 90 | 2.2k | 1.2k | 200 | — | 19 | 9 | — | — | — | 4.85M |
| 15 | 700 | — | 5k | 1.1k | 290 | — | — | 47 | 21 | — | 36.14M |
| 20 | 3.65k | — | — | 3.6k | 2.5k | — | 230 | — | 110 | 41 | 207.51M |
| 25 | 31.9k | — | — | — | 10k | 4.3k | 2.4k | — | 880 | 480 | 1.84B |
| 30 | 135k | — | — | — | 49k | 21k | 12k | — | 4.3k | 2.3k | 8.34B |
The number to watch in that table is the Centaurs’ health: it is what the rest of your group has to stay under. Anything stronger than that will pick a different target, and the Centaurs will fall on your siege engines instead.
What gets taken to each level.
| Citadel | Catapults | Tier | Troops |
|---|---|---|---|
| 10 | ~100 | II | Ranged only, plus Flying if you have them |
| 15 | ~320 | III | Mounted only, plus Flying if you have them |
| 20 | ~800 | IV | Melee only, plus Flying if you have them |
| 25 | ~3.2k | V | Melee only, plus Flying |
| 30 | ~1.05k | VII | Flying only |
Catapult numbers are orientative: they depend on your strength bonuses and on some other features.
The walls, that no reinforcement can reach you inside, the Clan Chest on top: all of that is the same whichever of the two you are marching on.
