An obsidian block reinforced with stone. From top to bottom, as shown by /cti: durability, NameLayer group, reinforcement material.
Citadel is a common plugin on civ servers which allows blocks to be reinforced at the cost of resources. Reinforced blocks must be broken many times before they are destroyed. The durability of a reinforced block can be increased by reinforcing it with a more expensive material. Reinforced blocks also prevent certain player interactions, such as a reinforced door from being opened.
Citadel interacts closely with the Namelayer plugin. Blocks are reinforced to a particular Namelayer group, and users on that group can bypass the protections of Citadel for that block.
Citadel is primarily used as a defensive tool. Players generally reinforce their builds, or defensive structures like vaults, to make them harder to grief or attack.
First introduced in Civcraft, Citadel has been included in every mainline civ server since.
In vanilla minecraft, blocks need only be broken once to be destroyed. In contrast, blocks reinforced by Citadel must be broken repeatedly before the block is destroyed. The durability of a reinforced block depends on the material that block was reinforced with.
A reinforced block being destroyed. Each time the block is broken, it reduces the reinforcement durability. The block is destroyed once the durability reaches zero.
Unless they have permissions on the Namelayer group the block is reinforced to, players cannot interact with reinforced blocks in any way. This includes:
Opening reinforced containers, such as chests, barrels, or hoppers
Pulling items out of — or putting them into — a reinforced container with a hopper (unless the container has been marked as insecure)
Opening or closing reinforced apertures, such as doors or trapdoors
Tilling reinforced grass or destroying reinforced farmland
Initiating a redstone signal from a reinforced redstone component. Stepping on a reinforced pressure plate or clicking a reinforced button, for instance, will not send a redstone signal
Harvesting or planting crops on top of a reinforced block
Tool Durability
Breaking a reinforced block will not take durability off a tool. However, performing the final break which destroys a reinforced block will. This means that destroying a reinforced block with a tool consumes the same durability as breaking a regular block.
Gravity
Reinforced blocks are not affected by gravity. This means that, for instance, reinforced sand will float, even when unsupported by blocks under it.
However, blocks which require a supporting block to be placed on — such as doors, rails, buttons, or torches — still have this requirement, even if they are reinforced.
Modes
Citadel has several modes which players can enter into or exit from at any time. These modes change how players reinforce blocks or interact with reinforced blocks.
These modes change the mechanism by which players reinforce blocks.
By default, players are in Normal mode, which does not allow blocks to be reinforced.
Reinforce Mode
/ctr [group]
Reinforce mode is the most basic reinforcement mode. While in Reinforce mode, left or rick clicking on a block with a reinforcement material in the player's hand will reinforce that block.
group is the NameLayer group blocks will be reinforced to. If not supplied, it will use the player's default group.
Fortify Mode
/ctf [group]
The command for Fortify mode must be run while holding a reinforcement material in the player's hand. While in Fortify mode, any blocks the player placees will automatically be reinforced with that material. If the player runs out of reinforcement material, or a reinforcement fails for any reason, Fortify mode will exit.
group is the NameLayer group blocks will be reinforced to. If not supplied, it will use the player's default group.
Easy Mode
/cte
While in Easy mode, left clicking a block with a reinforcement material in the player's hand will reinforce that block. Although similar to Reinforce mode, Easy mode allows players to right click blocks without the risk of accidentally reinforcing them. Additionally, Easy mode does not take a group argument, and can only reinforce to a player's default group.
Advanced Mode
/cta [group]
The command for Advanced mode must be run while holding a block in the player's main hand and a reinforcement material in the player's offhand. Until Advanced mode exits, whenever that block type is placed, it will be reinforced with the corresponding material.
The command for Advanced mode may be repeated multiple times to tie different block types to different reinforcement materials. These associations last only until the player exits Advanced mode.
group is the NameLayer group the corresponding block type will be reinforced to. If not supplied, it will use the player's default group.
Patch Mode
/ctp
Used to repair existing reinforcements instead of creating them. While in Patch mode, left or right click an existing reinforced block. It will be repaired to full durability if you have the reinforcement material used to reinforce the block in your inventory. The chance of consuming the reinforcement material is proportional to how damaged the block is. For instance, a block at 95% durability would have a 5% chance of consuming the material.
Normal Mode
/cto
Exits any reinforcement mode and returns to Normal mode. This is the default mode for all players. While in Normal mode, reinforcements cannot be created.
Toggle Modes
These modes allow you to retrieve information about reinforcements or affect reinforcements in some other way besides creating a reinforcement. These modes can be toggled on or off independently of a reinforcement mode or of each other. In other words, you could have info mode, bypass mode, and reinforce mode all active at the same time.
Insecure Mode
/ctin
Insecure mode allows you to left click a reinforced container to turn it into an "insecure" reinforcement. An insecure reinforcement allows hoppers to move items in and out of the container, in contrast to a normal reinforcement, which will not.
Info Mode
/cti
While in Info mode, left or right clicking a block will cause information about its reinforcement to be displayed, including its reinforcement material and durability. This can be used even on blocks reinforced to a group you do not have permissions on.
Bypass Mode
/ctb
Bypass mode allows you to bypass reinforcements on a group have permissions on. This means that you can treat reinforced blocks as unreinforced blocks when in Bypass mode. When breaking a reinforced block in Bypass mode, the reinforcement material originally used will be returned to you.
An acid block is the name given to a particular block which can be used to clear reinforced blocks at scale, without manually breaking each reinforced block. Gold blocks have historically been used as acid blocks since their introduction on Civcraft.
To use an acid block, place it underneath a reinforced block, then reinforce the acid block with the same material that the block above it is reinforced with. Depending on this material, the acid block will take a certain amount of time to mature (see § Reinforcement Materials). Once matured, run /ctacid while looking at the acid block to destroy the block above it. This works regardless of how much durability the reinforced block has. Only users with permissions on an acid block's reinforcement group can run /ctacid on it.
/ctacid can be run on many acid blocks simultaneously, as long as they are all beneath the player's cursor when the command is issued.
Note that an acid block does not gradually do damage to the block above it. It only has an effect once it matures and someone runs /ctacid on it.
Acid blocks is one reason why almost all defensive infrastructure (such as Vaults and Bunkers) are built at bedrock. Building on an unbreakable block such as bedrock prevents acid blocks from being used against you.
Reinforcements can decay if nobody on the group they are reinforced to logs in for a certain amount of time. For instance, if nobody on a group logs in for 3 months, all blocks reinforced to that group will get a damage multiplier of 2 (meaning they require half the breaks to break).
Since a single player on the group logging in is enough to reset decay, decayed reinforcements are uncommon.

Redstone Interactions
TODO rewrite as paragraphs
Reinforced buttons will only emit a signal if someone from the namelayer is nearby (distance?)
Comparators cannot inspect the content of a reinforced container block (e.g: chests, furnaces, droppers)
Droppers and hoppers will not transfer items if the destination block is not on the same reinforcement group.
Blocks can not be attached to a reinforced redstone component (e.g dropper, dispenser, hopper?) if not on the reinforcement groups.
Reinforced doors, trapdoors and fences gate will only respond to a redstone signal if someone on the reinforcement group is less than 7 blocks away from it [2]
