The Watcher

"Congratulations, you made it through the Entrance. I have been watching you closely... Unfortunately, for now, this is the end of the road. I sense many dead spirits eager to return to the living.. I will bring some of them back. Watch this."

- The Watcher (Catacombs Entrance)

The Watcher is the of Catacombs Entrance of The Catacombs Dungeon. He appears in all of the following floors, acting as a players must defeat before moving on to the main boss of the floor.

Necron has a connection to The Watcher, calling it 'The Eye' by mentioning it in his first welcome speech.

Lore
Stalker

This strange creature is roaming The Catacombs to add powerful adventurers to its collection.

The Fight
The Watcher will summon undead spirits from the display cases on the walls. Players can not directly damage the Watcher and must instead kill all the spirits in order to win the fight.

Players who are dead when the fight starts or die during the fight are reanimated as a hostile Wandering Soul that resembles the player who died. Killing a Wandering Soul will revive the player it resembles.

The Watcher will stop summoning spirits after set amount of Undead have been spawned. Note that the Undead have high amounts of Defense, causing them to take low amounts of damage. Players win the fight after they have defeated all the spirits, as the Watcher itself cannot be damaged. When attempting to attack it, it will say "I am not your enemy." or "Stop attacking me.". The Watcher will proceed to zap a laser toward the player, dealing high amounts of damage.

This fight increases in difficulty and gains mechanics on higher floors.

Arena
The Watcher's arena is fairly simple. There are 4 chains in the room with the Undead's and Player's heads on the wall. There are some corridors behind the Undead wall. A way to cheese the boss up to Floor III is to go on top of the portal, entrance door, or go on the second layer of the Undead. Keep in mind the top of the exit portal changes on every floor to represent the boss of that floor.

Floor 2
Starting from Floor 2, the Undead gain special perks unique to their type.

Floor 3
During Floor 3, Bonzo is reanimated at the start of the fight. There are some distinctions between Bonzo during this fight and during his debut in Floor 1. Bonzo doesn't revive and he will instead have 300,000 health instead of his original 250,000.

Floor 4
On Floor 4 or above, the Watcher will be next to 2 Watchful Eyes, which deals heavy damage to players who attempt to stay away from the fight off and stay on platforms. Scarf also has a chance of being reanimated instead of Bonzo.


 * You can lure the mobs out of the blood room and then leap onto a platform outside the blood room in order to not get zapped by the Watchful Eyes.

Floor 5
All mobs spawned by The Watcher gain a random modifier:
 * Speedy increases the mobs' speed, and gives a chance for the mobs to drop Dungeon potions on their respective floor on death.
 * Stormy allows the mobs to strike lightning on nearby players, and gives a rare chance to drop Thunderlord VI Enchanted Books on death.
 * Healthy increases the mobs' maximum health, and gives a chance to drop Healing Tissues on death.
 * Boomer makes the mobs drop primed TNT on death and drop Superboom TNT. (Note: The primed TNT deals 100% of the caught players' health as True Damage, meaning it instakills all players in range unless the player has Absorption or Wither Cloak Sword active.)
 * Stealthy makes the mobs invisible except for their name tags and armor.
 * Golden makes the mobs drop Gold Essence on death.

The modifier will be announced before the fight begins. For example, when Boomer mobs are summoned, The Watcher will announce "These will be stubborn and unwilling to change!" before the first summon.

Floor 6
The Watcher no longer announces the modifier of its summons before starting.

Livid has a chance to be reanimated instead of Scarf or Bonzo. Upon death, Boss-type undeads have a chance to drop their respective Fragments, which can upgrade items related to them. Bonzo Fragments dropped from Bonzo can upgrade the Bonzo's Staff and Bonzo's Mask, Scarf Fragments dropped from Scarf can upgrade the Adaptive Blade and Adaptive Armor, Livid Fragments dropped from Livid can upgrade the Shadow Assassin Armor, Shadow Fury and Last Breath.

Floor 7
At the beginning of the fight, before Bonzo, Scarf or Livid is summoned, one of Sadan's giants (The Diamond Giant, Jolly Pink Giant, Bigfoot, or L.A.S.R.) will be reanimated. The pillars will be removed in the arena, making space for the Giant. Each one has a chance to drop its respective Precursor Relic, which can upgrade Wither Armor dropped from Necron.

Battle Hints

 * If The Watcher says "You'll do.", "This guy look likes a fighter." [sic], "Let's see how you can handle this.", "Go, fight!", "Hmmm... This one!", or "Go and live again!" he will summon a spirit.
 * Look at the display cases on the walls. You'll get a general idea of how the fight's going to be. Note that the Watcher will only summon some of the spirits in the cases.
 * Once The Watcher says "That will be enough for now." he will no longer summon spirits.
 * The Watcher is immune to Arrows and other ranged projectiles. Hitting him with one will deflect it and will make him shoot you with a laser.
 * One of the best ways to clear The Watcher summons is to use Ice Spray Wand ability on them, and use a high Damage weapon with Mage Beam to kill them.

Loot

 * On defeat, he will drop 2-3 dungeon blessings.
 * Blessing of Life
 * Blessing of Power
 * He can rarely drop Optical Lens.

Trivia

 * Despite the name similarities, The Watcher has nothing in relation to the Watchers in the Dragon's Nest.
 * In the Journal - The Eye, it is shown that The Watcher was related to Sadan's interest in Necromancy.
 * The Watcher's eye resembles the Demon Eye from Terraria. This is further supported by the fact that both have a chance to drop item called "Optical Lens" upon their defeat.
 * The Watcher fight could be inspired by the first phase of the Brain of Cthulhu fight in Terraria, where it becomes invincible and it summons minions you must kill.
 * The Watcher will revive a player when their Wandering Soul was killed, if Wandering Soul is killed after the respective player was revived otherwise it won't have any effect.
 * The color of The Watcher's eye starts changing from a vivid green to a sickly yellow the deeper you go in the Catacombs, which slowly turns more orange when going into Master Mode.
 * Before becoming The Watcher, he was a human know as Lanthrop, he was a pupil and adopted son of after his parents died during the Calamity. Ever since  on top of the mountain has opened, Lanthrop started getting visions of a floating eye. One day he is asked by Dr. Emmet to deliver a letter to his colleague in  so he heads out, for some reason feeling sad looking at the house he lived in. Entering the inn, he was getting the feeling of Deja Vu. In the inn he saw a man with black hair in black clothing. He recognized this from one of his visions. The mysterious man then leaves upstairs, a different man, a young assassin named Livid, comes to Lanthrop and questions him about the mysterious man, since he claims to have never seen in the inn before. Lanthrop gets another Deja Vu from his conversation with this man. Lanthrop answers Livid's question saying that the mysterious man is a merchant from far away land, not knowing what lead him to say that since he in fact didn't know him. Livid then leaves back to his table and Lanthrop too goes upstairs. A while after, the mysterious man then left the inn carrying Livid with him. Lanthrop decides to follow him, as his feeling of Deja Vu grows stronger, despite him not remembering this. Necron figures out he is being followed and before the wooden entrance to  he asks his pursuer to his reasoning. Lanthrop then explains that in his visions he saw that by following Necron to his his master, he will reach his full potential, as the door opened on their own, Necron urged Lanthrop to follow him. In Catacombs he meets with Kaeman who shortly after led him to his laboratory, in from of the Seeing-Stone, which immediately triggers a vision in him, in which the command "Find me", after slowly focusing on the vision, he sees a house with a woman and a child inside, he recognizes the source of the command, Kaeman. The Wither King was impressed by Lanthrop's natural abilities and in the following months, he made him use the Seeing-Stone again and again. Lantrop's eyes improved dramatically, but he slowly began to lose control of the rest of his body. Kaeman was resolute in unlocking Lanthrop's potential, and anything that hindered that goal had to be removed. As Lanthrop's limbs became a burden, they were surgically removed, starting with his legs and then his arms. When Kaeman had finished his experimentation, Lanthrop was no longer alive, nor was he dead. His eyes had grown and merged together, while everything else had been lost. Lanthrop was no more, and he was now The Watcher. Some time after, Kaeman has asked The Watcher to see Kaeman's past and use the orb to create a world, identical to the one Kaeman once knew, in which he could once again be happy. This task was difficult, but Watcher was determined to please his master, and after long studying of Kaeman's past, so much that he knew his family more than he knew himself, he has succeeded. Kaeman thanked the Watcher, which was a rare display from him and told him to be loyal to his new master - Necron, while he decided to stay in an enclosed chamber, dreaming of a happier time. After the seclusion of their Master, Necron decided to gather an army of necromancers for his goal and Watcher at some point wrote most of the Dungeon Journals.
