The Concierge

The Concierge is first tier 1 boss in the game. It is encountered on the Black Bridge.

Moveset
In 1+ BSC, the Concierge goes straight to the second phase.

Vulnerabilities

 * Vulnerable to magnetic fields, but can still leap at the player.
 * Doesn't focus attacks on turrets, unlike most enemies.
 * Most attacks can be cancelled by stun effects.

Primary attacks
Stab
 * This attack has a long, clear telegraphed wind-up, so it's easy to prepare any viable counters.
 * The attack can be blocked and dodge-rolled but the best option would be to parry it, resulting in a short stun.
 * The boss will prioritize this attack if you are within the melee range of it.
 * This will make it possible to deal melee damage, parry the Stab and continue your combo.
 * In the second and third phase, this can be used to stop or delay the use of Aura of Laceration but it is not a perfect strategy because being slightly too far away will make the Concierge use the aura.
 * It will perform a Shout when going into the next phase which will push you away.

Fire strike
 * This attack has a long, clear telegraphed wind-up, so it's easy to prepare for it.
 * This attack can only be jumped over or blocked and doesn't severely open up the boss to a counter-attack as he will continue attacking before the fire reaches the edges of the arena.
 * The best option is long-range attacks or skills.

Leap
 * The leap can be crouched under at its peak and be at any point during its duration.
 * The leap can be interrupted by a if close enough to the starting point of the leap.
 * In later phases, the boss will use this attack after creating an Aura of Laceration which makes it so crouching under or parrying it still result in damage to the player.

Defensive attack
Shout
 * This is attack is performed during phase changes and cannot be interrupted or blocked, only avoided by being out of range.

Aura of laceration
 * Unlike the other attacks, this one has a short wind-up and the only hint that the Concierge is using it are little red particles.
 * This still distinguishes it from the other attacks and thus is still clear that the aura is the upcoming attack.
 * This attack will only be used if you are out of melee range of the boss.
 * As the aura does multiple ticks of damage on contact, it is impossible to do any close-range damage, so far ranged attacks are the best option here.

Weapons/Skills

 * All weapons are viable against this boss as long as you can dodge. You may want turrets and bombs, or to stun it. Parrying is very effective against both Stab and Leap.  is also a viable skill to take against the Concierge as it negates all of his attacks and leaves him vulnerable for long periods of time.

Lore

 * The Concierge was the prison's warden, Castaing. He was in charge of controlling the prison's entrance and managing prison guards.
 * Castaing received secret orders from the King to stop controlling entrances to the Prison and to keep all prisoners inside, even those who had finished their sentence . He publicly posted a sign asking for citizens to report any signs of infection or odd behavior but was scolded by the King for making his secret orders public.
 * The King later asked Castaing to focus on preventing imprisoned villagers from crossing the bridge and escaping back to their homes, by force if necessary. It is unclear if those prisoners were infected, but it seems they were not guilty of any crime.
 * Castaing became ill from the Malaise, which led to him mutating into the Concierge monster.
 * It is implied that Castaing was taking bribes from an unknown person and at least partly disobeying the King's orders. His motivations are unclear, but it seems Castaing needed money to support his lazy, rich lifestyle, as indicated by his sunbathing crib on top of the Ramparts.
 * Castaing had a number of offices around the Island, notably in Prisoners' Quarters, the Promenade of the Condemned, the Ramparts, and the Prison Depths.
 * Castaing had a book titled "Directing a Prison for Dummies", which includes a chapter on "bridge construction". This is a reference to the Black Bridge where the Beheaded fights him.
 * He was sometimes referred to as "Commander Castaing" in a letter found from a body of the deceased Royal Gardener. He warns the Gardener to stop, as his actions are an inconvenience to him.
 * One lore room contains a letter from Castaing to his soldiers, which the Beheaded states is a direct copy from "Managing soldiers: How to earn their respect without using torture", one of the books Castaing has.

Trivia

 * Before the Baguette Update Alpha, the boss' name was The Incomplete One. During the earlier stages of development of the Baguette Update, he was known as The Caretaker.
 * A concierge is a person in charge of a building's entrance. The Concierge is fought on the bridge that leads to the island's prison, making it an apt title.
 * The Concierge is always the boss in the Daily Run. With this specific version, he has nerfed health, and never uses his defensive abilities.
 * The enemy derived from him is the Sweeper, who imitates his flame strike attack.
