Voidgloom Seraph

"If Necron is the right-hand of the Wither King, this dark demigod is the left-hand."

The Voidgloom Seraph (/ˈsɛrəf/, "the burning one"; plural Seraphim /ˈsɛrəfɪm/) is a Slayer Boss in the Enderman Slayer branch. It is an Enderman with strong attacks. It is significantly stronger than the previous Slayer bosses.

Defeating the Voidgloom Seraph results in unlocking the Blaze Slayer quest and the Inferno Demonlord boss.

Behavior
The Voidgloom Seraph is an Enderman-type mob hostile to all players. It has the appearance of an enderman with critical particles following it. It has a smaller aggro range compared to other Slayers.

Half the damage of all Voidgloom Seraphim is dealt as AoE damage, damaging all players fighting the Seraph in range.

Occasionally, it will teleport behind or to the side of the player it is attacking. This teleport ability has unlimited range. The Seraph will only teleport if the player is moving, and with increased chance if they haven't attacked in a while. The Seraph will never teleport during its shield phase.

All Voidgloom Seraphim are immune to the abilities of Aspect of the Dragons and Ice Spray Wand. They are immune to water damage. Like normal Endermen, they are also immune to most arrows, except those from Juju Shortbow and Terminator.

Upon spawning and upon reaching 2/3 and 1/3 health, it protects itself with a Malevolent Hitshield. This shield has no invincibility frames, meaning high CPS(Clicks per second) and can go through the Hitshield faster. However, each hit drains the shield by 1 regardless of damage. All types of arrows can damage this shield. In this state, it cannot teleport. Purple particles surround the Seraph when its shield is up. Upon being destroyed, it resumes attacking as normal.

When the Voidgloom Seraphim's Hitshield is not active, that is effective on them is divided by 4.

As with all Slayer bosses, if the Voidgloom Seraph has not dealt damage to a player for some time, it will begin rapidly regenerating. The regeneration immediately stops when it hits a player again. If 4 minutes pass without the boss being defeated, it will despawn, failing the Slayer quest. A timer is shown above its head indicating the remaining time.

Voidling Fanatic and Voidling Extremist spawns are suppressed in the vicinity of a Voidgloom Seraph.

Each tier has all of the abilities from the ones before it.


 * Malevolent Hitshield appears upon spawning and reaching (2/3) and  (1/3). It has 15 hits. The boss does not gain DPS while the shield is up.


 * Malevolent Hitshield appears upon spawning and reaching (2/3) and  (1/3). It has 30 hits. The boss does not gain DPS while the shield is up.


 * Yang Glyphs appear upon reaching (1/2).
 * The Seraph will begin to hold Yang Glyphs, which appear as a beacon. After 2 seconds, it will throw the glyph to a nearby spot. Any player fighting the Seraph can destroy the glyph by standing adjacent to or on top of it. If it is not destroyed within 5 seconds, it deals  in  to all players fighting the Seraph. The abilities of the Mithril Coat and Wither Cloak Sword can block this damage. Glyphs cannot be thrown when the Hitshield is up. The Seraph will continue to try to throw Glyphs until it is defeated.


 * Malevolent Hitshield appears upon spawning and reaching (2/3) and  (1/3). It has 60 hits. The boss gains +3,000 DPS every 3s the shield is up; this bonus DPS is removed once the shield is destroyed.


 * Yang Glyphs begin at (2/3) and are thrown more often.


 * Nukekubi Fixation heads spawn around the player it is attacking upon reaching (1/3). The heads can be destroyed by looking directly at them for 0.5s. They can be destroyed through walls. When they are destroyed, they will play a hissing sound. Each head attacks with a faint blue laser, and deals base 800 DPS, which is doubled for each head alive.


 * Malevolent Hitshield appears upon spawning and reaching (2/3) and  (1/3). It has 100 hits. The boss gains +3,000 DPS every 3s the shield is up; this bonus DPS is removed once the shield is destroyed.
 * Yang Glyphs begin at (2/3) and are thrown at the same rate as.
 * Nukekubi Fixation heads spawn upon reaching (1/3). Each head deals base 2,000 DPS, which is doubled for each head alive.


 * Broken Heart Radiation occurs at (5/6),  (1/2) and  (1/6) (At  (2/3) and  (1/3), Malevolent Hitshield is active. So at both of the healths, Voidgloom Seraph wouldn't activate Broken Heart Radiation).
 * The Seraph becomes invulnerable and stops moving for 8 seconds, taking the appearance of being seated. Explosion particles appear centered on the Seraph when this starts.
 * During this time, it casts 12 Broken Heart Radiation beams: 4 groups of 3 20-block long beams, stacked 1 block on top of each other, each group at 90° to each other. The beams pass through walls. The beams rotate clockwise for the duration, completing 1 full rotation in the 8 seconds. They begin blue and change to purple, then green over the duration.
 * Any player fighting the Seraph who comes into contact with a beam takes 25% of their health as true damage and has their healing reduced by 12% for 90s. The healing reduction stacks. In addition, any player fighting the Seraph who steps out of reach of the beams begins to take damage rapidly.
 * Yang Glyphs and Nukekubi Fixations can be thrown in this phase.

Minibosses
These are possible Minibosses that could spawn upon killing a Enderman when a Voidgloom Seraph Slayer quest is active. It is also possible that after killing one of these minibosses, another could spawn immediately.

Trivia

 * The Voidgloom Seraph used to have, one of the highest  of all non-dungeon enemies in the game.
 * Yang Glyphs and Nukekubi Fixation heads can be thrown through walls, and in extremely rare cases, to inaccessible locations. For Yang Glyphs, players can use Wither Cloak Sword's Ability, Creeper Veil to survive. Heads can still be destroyed by looking them.
 * Thrown Yang Glyphs can sometimes replace blocks such as stairs, end stones and glass panes. When the Glyph is destroyed, the block will not be replaced until the server restarts.
 * When using Broken Heart Radiation, the particles from the Seraph teleporting to the player will sometimes show. The Seraph will not move.
 * The Seraph's invulnerability during Broken Heart Radiation does not start until the lasers are fired, leaving a brief period of vulnerability in the transitional phase.
 * If a Voidgloom Seraph despawns while attacking with Broken Heart Radiation, the beams will persist indefinitely. These beams are visual only.
 * Its name may be a reference to Seraph of the End.
 * The name of Nukekubi Fixations are a reference to nukekubi, a mythical creature in Japanese folklore whose head detaches from its body.
 * When in the Malvolent Hitshield, it can take damage using bows other than the Juju Shortbow and Terminator, making it easy to quickly defeat the shield.
 * The Voidgloom Seraph does not take damage from water and attacks less when in water.
 * If a player deals enough damage to a Tier 4 boss just as Broken Heart Radiation triggers to also trigger Malevolent Hitshield, the boss will not throw Yang Glyphs during this and immediately start in the Hitshields phase after the lasers complete their full rotation.
