Citadel

Citadel is how you protect blocks on FortressMC. Spend materials to add HP to blocks so they take many breaks to destroy. Unlike faction plugins, protection is per-block: anyone with enough time and picks can break through.

Reinforcement materials

Hold the material in your hotbar or offhand (offhand takes priority). Left-click a block to reinforce it, or hold the material while placing blocks to auto-reinforce on place.

How it works

  1. Place and reinforce: hold a reinforcement material and place blocks. One material is consumed per block.
  2. Left-click to inspect: see the HP hologram, reinforce a bare block, or upgrade to a stronger tier.
  3. Maturation: new reinforcements start at 0 effective HP and gain 1 HP every 5 minutes. Fresh reinforcements are vulnerable until they mature.
  4. Breaking: each break attempt deals 1 damage. The break is cancelled while HP remains. When depleted, the material drops.

Upgrading requires a strictly stronger tier (higher max HP).

Entity reinforcement

Armor stands, minecarts, and boats can be reinforced on placement when entity reinforcement is enabled in config.

Bastions

Bastion uses Citadel HP on beacons and conduits. City bastions block enemy reinforcement inside the field. Vault bastions block many actions entirely.
