Necron

"Necron"

Necron is the of The Catacombs in The Catacombs - Floor VII and is the Right-Hand Man 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. 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. The second is a frenzy where explosions are centred on him, killing any player who gets close. It is only used in phase 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 three of the four pillars, with Necron destroying it and becoming enraged. After three pillars have been destroyed by Necron, 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.

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. Wither Guards should be ignored as much as possible, since Necron will constantly respawn them, and fighting them does not contribute to the Boss Fight. After getting the crystals, the whole team should run to the laser to trap Necron in it.

Phase 2:
For phase two, it is recommended that the everyone uses whatever weapons they can such as the Spirit Sceptre or Yeti Sword to kill the Wither Miners at the bottom while Necron brings the player down. 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. 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. Its homing ability and ricochet also make it a good choice to use with so many mobs in close range. 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, 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 will not catch up. A Berserker can also do this with the Phantom Rod as well as a Mage doing this with their left click attack.

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 can deal extra damage per second. 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. For some reason, 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.)
