Necron

"Necron"

Necron is the of The Catacombs in The Catacombs - Floor VII and is the Right-HandMan of the Wither King. He killed The Professor by smiting him to death.

Lore
Right hand of the Wither King. Inherited the Catacombs eons ago. Never defeated, feared by anything living AND dead.

Boss Fight
Necron has and 300 or 400(Not confirmed) [verify]. He has a shield surrounding him which protects him from all attacks. When he is brought under the laser in phase 1, crushed in phase 2, or in phase 4, he loses the shield.

Necron has 2 attacks. The first is a barrage of wither skulls launched from each of his 3 heads. They do high damage and are fired rapidly, as well as dealing large quantities of True Knockback. The second is a frenzy where explosions are centered on him, dealing extremely high amounts of damage to any player who gets close. The latter is used in phases 2 (when enraged), 3, and 4.

Phase 1
Necron's first phase involves the players being in a factory-like arena. Necron himself along with Wither Miners and Wither Guards will knock players around the arena, along with his immunity to attacks. There are two podiums with an empty space on them, and players have to put an Energy Crystal on them. To get the Energy Crystal, players have to complete a parkour in the arena. The lava can launch players up in the air to jump-start the parkour. Be wary of the Wither Guards and Necron as they can knock players off of the parkour. Once the player gets to the Energy Crystal, punch it to get a crystal and then place it on the podium. The parkour must be done again to retrieve and place down the second crystal. After this, players will need to lure Necron into a laser that appears on the center of the conveyor belt. Necron will then freeze in place and players will be required to attack him. Bringing him to 75% health will trigger phase 2. Failing to do so will enrage Necron, making him attack really fast for a short amount of time and also resetting the crystals positions, looping it until the 75% health requirement is reached.

Phase 2
The factory's second layer is exposed; within it are four pillars. Wither Guards and Miners will still appear here, with a Shadow Assassin spawning in in each corner. Each pillar can be used to damage Necron. A player has to go to an area that controls the pillar, which will raise and lower it if they stand on it long enough. The goal is to trap Necron in the pillars. When he is crushed, he will become vulnerable for 10 seconds and will then enter an enraged state. After three pillars have been destroyed or Necron reaches 50% health, the last pillar that Necron destroys will open up a hole, revealing the third and final layer of the factory.

It is also possible to trigger the third phase in one or two pillars if the players have enough damage per second to reduce Necron's health down to 50%.

Phase 3
Necron's third phase involves players running and parkouring throughout the factory, all while activating Terminals and switching levers. Players will need to outpace Necron in a race. Be quick, as Necron's frenzy will instantly kill any player who falls behind.

It is possible to slow Necron down by hitting him, although it doesn't slow him down by much. It is recommended to have the mage or the archer use mage beams or arrows, respectively, to rapidly attack Necron to buy time for their teammates.

Phase 4
After completing the third phase's puzzles, Necron will then jump to the bottom of the factory with a platform surrounded by a ring of lava. He then stays in the middle of the platform. After taking enough damage, he will go back to the middle of the room to rest. During which dealing damage to him aggravates him and causes him to attack again. Failure to damage him while he is in the middle will increase the blast radius Necron's frenzy attack and instantly kill anyone who stands within that radius. Necron can also destroy parts of the arena as the phase progresses. Once players have reduced Necron's health to nothing, they win the fight.

Be aware that taking too long will result in Necron destroying most of the platforms, making it much more difficult to avoid him.

Strategy
Players can't use any form of movement abilities and items such as Aspect of the End or Ender Pearl in every phase. However, the Rogue Sword can still be used to gain extra walk speed. If the player has jump boost, it will be removed at the start of the fight. However, a Jerry-chine Gun or a Bonzo Staff still works, so it is possible to move around using the knockback from them.

Due to Necron having extremely low (being only 300), successfully using a Last Breath to shoot him twice with 2 other players will essentially make Necron take 4 times the damage he would normally take.

Because Necron has 99% Magic Damage resistance, Mage players should heavily rely on Mage beam damage, and with whatever weapon they use they should always left and right click consistently. It is recommended for mage players that have enough to reforge some pieces of armor to Ancient, and their mage weapon to Withered.

Phase 1
For phase one, it is recommended that one player that has large amounts of lifesteal and survivability to keep Necron occupied by constantly attacking him. Other players should not attack Necron but instead focus on getting the Crystals to the platforms, which can be done immediately by hopping up a wall by using a Jerry-chine Gun or by using a Bonzo's Staff to bounce off the walls after jumping in the lava pools. If the player has trouble jumping up to the crystals due to wither skulls, the player is advised to kill the impeding Wither Guards, even though Necron will constantly respawn them. After getting the crystals and placing them down on the pad, the whole team should run to the laser to trap Necron in it.

Phase 2
When the team is descending from the 1st phase room to the 2nd phase room, they can choose if they want to "pre-fire". Pre-firing refers to killing the Wither Miners on the floor during the descent. This technique can speed up runs slightly, but causes a large number of death skulls to be fired, which can kill players without sufficient health. Regardless of whether the team chooses to do so or not, the decision should be communicated to all team members and followed, as a single person pre-firing can also cause damage.

If one has Wither Impact, they can use its ability on the way down to gain an absorption shield to survive better.

After the player is completely descended, the player may use whatever weapons they can such as the Spirit Sceptre or Yeti Sword to kill the Wither Miners. When engaging with Necron, only one player should attack Necron such that Necron does not change targets constantly and change his position under the pillar.

One player should head to the pad and stand in the middle so that Necron can be crushed under a pillar, usually starting with the purple one. Whenever Necron is crushed, the players should deal as much damage as possible. Getting Necron down to half health allows all other pads to be skipped. It is recommended to use a Wither Skeleton Pet to deal maximum damage to Necron.

Ranged weapons like the Flower of Truth, Spirit Sceptre, or the Bonzo's Staff are recommended as it does not require the player to stand right next to the Boss and melee it. The former's homing ability and ricochet also make it a good choice to use with so many mobs in close range. However, due to Necron and the other mobs being rather tanky, those weapons may not be as viable if a players want fast runs. Instead, for more experienced players, they should use a dungeonized 100m Midas Staff or a Hyperion with all three scrolls. Players should also eliminate the Wither Archers that are lined along the walls of the room; this will make the boss fight easier to finish because players don't have to dodge so many projectiles. Be sure not to lure Necron to the red corner of the room as it is a glitched chunk and will softlock the fight.

Phase 3
For phase 3, for inexperienced players it is recommended that an Archer does not do the puzzles but rather slow down Necron with Bonemerangs in order to buy more time for everyone to finish the puzzles and ensure Necron does not catch up. A Berserker can also do this with the Phantom Rod as well and Mage s can do this with their left click attack.

More experienced players may skip past entire parts of this phase and do terminals ahead by using a Jerry-chine Gun to scale the gates.

Phase 4
For phase 4, it is recommended that the Tank should try to stay in the corner of the slabs in the pillar to allow the Mage, Berserker, and Archer to deal extra damage per second. If there is no Tank, whoever is the tankiest should always go into a corner of a pillar, or whoever Necron is attacking.

When Necron goes to the middle, have a Mage click on him at first using either left click attack or Spirit Sceptre, allowing the Archer and Berserker to go into the middle area and do more damage. If Necron is taking a lot of damage, his blast radius gets smaller, allowing massive amounts of damage to be dealt. (This is a little risky, since sometimes Necron can still kill nearby players, but can make the run a lot faster.)

More experienced players should always call out who will be going to middle(normally being the Archer), and as soon as that person descends from phase 3, they should go to the middle and camp the edge closer to Necron, as to not get knocked into the lava. Whenever Necron heads to the middle, players should teleport to that person immediately and damage Necron.
