The Nation Core is a placeable block that acts as your nation’s heart. Standing near it inside
your own territory strengthens you, and during war it becomes a target enemies can siege and
destroy. Nation Cores must be enabled on your server.
This is separate from your capital chunk (/etnation setcapital) — you can have one, both,
or neither.
A Nation Core is forged at a Dragonforge station: 8 Hihiirokane Ingots, 8 Adamantite Ingots,
16 Magic Stone and 2 Earth Cores. See Forging for how the forge minigame
works.
Server admins can also grant one directly.
You need spending rights in your nation (the same rank that can touch the treasury) and you must
place it inside your own nation’s claimed territory. A nation can only have one Core at a
time.
If placement fails for any reason, the block is returned to you — placing never eats the item on
a failed attempt.
Sneak and right-click the Core with both hands empty and it shows a status card: tier, health,
the next tier’s price, and clickable [Upgrade] and — for the Sovereign — [Take down] links
(/etnation core remove does the same). Taking it down returns the block and resets it to tier 1.
You cannot do this while your nation is in an active or warming-up war.
If your nation disbands, an orphaned Core crumbles and drops its item the next time anyone clicks
it.
While your Core is intact, any nation member standing inside your own territory, within 8
claimed chunks of the Core (tier 1 default, server-configurable — see Tiers), gets:
The aura turns off automatically if your nation falls into treasury debt, and comes back the
moment you’re clear again.
A Core starts at tier 1 and can be raised to tier 4 from the nation treasury. Each tier
raises its siege health, how far the aura reaches, how strong the aura is — and how much war
score an attacker earns for toppling it. Defaults (server-configurable):
| Tier | Cost | Health | Aura reach | Aura regen / armor | War score if it falls |
|---|---|---|---|---|---|
| 1 | — | 5,000 | 8 chunks | +10% / +4 | 200 |
| 2 | $500,000 | 8,000 | 10 chunks | +15% / +6 | 300 |
| 3 | $1,500,000 | 12,000 | 12 chunks | +20% / +8 | 400 |
| 4 | $3,000,000 | 16,000 | 14 chunks | +25% / +10 | 500 |
Buy a tier from the status card, with /etnation core upgrade, or with the Upgrade Core button
on the Codex Nation overview. A Sovereign or officer with spending rights can buy; not while a war is
warming up or active, and not while the Core is shattered. An upgrade also refills the Core’s health.
The block shows its tier: the crystal alone at 1, an inner ring at 2, an outer ring at 3, orbiting
shards at 4.
During an active war (not the warm-up phase), a member of the opposing nation can attack the
Core directly — melee or ranged, same as attacking a player. Outside of an active war, or from
anyone not on the enemy side, the Core simply can’t be damaged (“The core is warded”).
A fallen Core is shattered, not destroyed — it stays in the world in a broken state and
drops one tier (never below 1). Its nation loses war score and nation season-ladder points,
and if the war ends with that nation losing, the winner takes an extra cut of their treasury on
top of normal war spoils.
Shattered and damaged Cores on both sides are automatically restored once the war is over,
whichever way it ends.
The Sovereign or an officer with spending rights can repair a damaged (not shattered) Core with a
right-click. It costs $1 in treasury money per missing HP (default, server-configurable) —
or nothing at all if your server isn’t running the nation economy.
Placing and repairing are done by interacting with the block. The rest has commands:
| Command | Does |
|---|---|
/etnation core status |
The status card (tier, health, next tier, action links) |
/etnation core upgrade |
Buy the next tier from the treasury |
/etnation core remove |
Sovereign only: take the Core down (tier resets to 1) |
Server admins can check status, force a repair, set a tier or grant a Core via /etadmin nation core.
