Inferno Demonlord

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

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

The Demonlord 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).

A shield protects the Demonlord, which can be attuned to, , , or. Only direct strikes from Blaze Slayer Daggers (Twilight Dagger, Firedust Dagger, Kindlebane Dagger, Mawdredge Dagger, Pyrochaos Dagger, Deathripper Dagger) attuned identically, as well as enchantment damage from those strikes, will deal full damage to the boss. Every 8 strikes with the correct attunement, the shield will change its attunement, in the aforementioned order. All other attacks, including ranged attacks, magic attacks, all strikes, and melee attacks from anything else will physically gain 10000, meaning to have their damage reduced by 99%.

The demons behave as before, but now have shields, which also 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. For example, when Quazii is spawned with or  and is hit correspondingly 8 times, Quazii becomes immune to damage and Typhoeus grants  or. Once Typhoeus is hit correspondingly 8 times, Typhoeus becomes immune to damage and Quazii grants or (The shields alternate). This process goes on until the demons are both defeated and the Inferno Demonlord reforms and resumes attacking.

Beginning at 50% HP, every 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). 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.
