Bastion
Citadel stops people from breaking your blocks, but it cannot stop them from placing grief inside your city. Bastions add an area-of-effect protection around reinforced beacons and conduits.
Requires: Citadel and Interaction Keys
City bastion (beacon)
A beacon becomes a city bastion when it is Citadel-reinforced and has a key bind. The lock does not need to be engaged.
| Property | Value |
|---|---|
| Field radius | Based on beacon pyramid tier (20 / 30 / 40 / 50 blocks for tiers 1-4) |
| Effect | Blocks enemy reinforcement inside the field |
| Damage to bastion | 2/20 Citadel HP on direct reinforcement block; 1/20 on overlap |
Use city bastions to protect farms, cities, and large areas where you need to stop enemies from reinforcing grief.
Vault bastion (conduit)
A conduit becomes a vault bastion when it is reinforced and the key bind is locked.
| Property | Value |
|---|---|
| Field radius | Vanilla conduit formula: floor(frameBlocks / 7) × 16 |
| Effect | Blocks block placement, buckets, pearls, chorus fruit, teleports, piston entry, fluid flow, and more |
| Damage to bastion | Same fractional HP model as city bastions |
Vault bastions are for high-security areas: vaults, pearl storage, wealth storage. They also block ender pearls, so pearling into a vault field is blocked unless you have the key.
Bypass
If you carry a matching key anywhere in your inventory (including shulkers), you skip all bastion effects.
