Inferno Demonlord

"Even demons fear this incarnation of pure evil, constantly feeding on it's burning desire for destruction."

- Maddox the Slayer

Inferno Demonlord is a Slayer Boss in the Blaze Slayer branch. It requires Voidgloom Seraph slain to start the  Boss.

The Inferno Demonlord shoots fireballs to its target rapidly, only dealing. When the boss is alive, it deals depending on its health if players fighting it goes into its aggro range. The boss splits into demons at 50% HP (1,250,000), named Quazii and Typhoeus (a Wither Skeleton and a Pigman appearance respectively).

Upon spawning, only Quazii can be damaged. Typhoeus will be immune. Quazii will behave more aggressively, whereas Typhoeus, while immune, will be repelled by the player when within 5 blocks of them. When Quazii is defeated, Typhoeus will adopt more aggressive behavior and can be attacked. When Typhoeus is defeated, the Demonlord reforms and resumes attacking.

The Demonlord splits into its demons once at 50% HP (5,000,000).

The boss has 99% Damage reduction from all sources. Only direct strikes from Blaze Slayer Daggers (Twilight Dagger, Firedust Dagger, Kindlebane Dagger, Mawdredge Dagger, Pyrochaos Dagger, Deathripper Dagger) attuned identically to the attunement of the boss's shield, enchantment damage from those strikes, as well as suffocation damage(deals 5% of the demons' health as ), will ignore the shield and deal full damage to the boss. Every 8 strikes with the correct attunement, the shield will change its attunement, in order of >  >  >  then it goes back to. All other attacks have their damage reduced by aforementioned 99%.

The demons behave as before, but now also have shields, which similarly to Demonlord change every 8 hits. Quazii will alternate only between and, while Typhoeus alternates only between  and. When a shield switches, the immunity between Quazii and Typhoeus also switches. Regardless the immunity, both demons walks towards their target, but whoever gets the immunity keeps walking and retreating within a 5 block radius of the target. For example, when Quazii is spawned with and is hit correspondingly 8 times, Quazii becomes immune to damage, leaves and Typhoeus grants. Once Typhoeus is hit correspondingly 8 times, Typhoeus becomes immune to damage, leaves and Quazii grants. This process goes on until the demons are both defeated and the Inferno Demonlord reforms and resumes attacking.

Beginning at 50% HP, every 20 seconds, the boss will prepare a fireball above its head for 3.5 seconds. Then, it will throw it in a random direction, where a 4-block high orange pillar will form. Such pillars must be destroyed within 7 seconds of being placed, by clicking them 8 times while having any Wisp Pet active. The pillar has no invincibility frames. The pillar gets 1 block shorter every two times it is hit until at 8 hits, it is no longer present. If it is not destroyed, all players fighting the Demonlord will take 1000 times their health as. This can be blocked by using the Wither Cloak Sword and Mithril Coat's abilities.

The Demonlord splits into its demons twice, at 2/3 HP and 1/3 HP.

Quazii gains a beam which spins slowly and is centered on Quazii's hitbox. If the player touches the beam, they will take 70% of their in, and Quazii will heal 20% of its health (1,000,000 hp at , and 2,000,000 hp at ).

Fire pillars begin at 2/3 HP (30,000,000).

Beginning at 1/3 HP (15,000,000), the boss will spawn up to 5 fire pits near the player regularly. Orange terracotta blocks will form in small cross shapes near the player, which turn to fire after 1.5 seconds. The fire deals 200% as  per second(meaning an instant kill with 100  or less, since it reduces the damage of bosses abilities ). Note that fire pits spawn immediately before the demons spawn as well as immediately after.

The Demonlord functions identically to previous tiers. It splits into its demons twice, at 2/3 HP (100,000,000) and 1/3 HP (50,000,000).

Typhoeus gains a trail of fire following it. The fire deals 60% of the player's as  if contact is made.

Fire pillars begin spawning at 2/3 HP. Fire pits begin spawning at 1/3 HP.

Trivia

 * Because of vanilla Minecraft AI and abilities, Typhoeus is stronger than Quazii. Therefore, the Firedust Dagger, Kindlebane Dagger and Pyrochaos Dagger are respectively stronger than the Twilight Dagger, Mawdredge Dagger and Deathripper Dagger if the Burning Vengence ﬗ ability is counted.
 * If both Quazii and Typhoeus spawn in a place which is one block large and get pushed, Quazii always gets pushed into the wall and take suffocation damage first.
