Inferno Demonlord

Inferno Demonlord is the boss of the Blaze Slayer. It unlocks once you beat a tier III Voidgloom Seraph.¹ Start quests with Maddox the Slayer, a Maddox Batphone or an Abiphone. Blazes in the Stronghold and the Smoldering Tomb, and Ashfang himself, fill the quest's Combat XP bar.¹²

The fight

The Demonlord burns everyone near it for true damage every second, more as its health drops. Its fireballs only knock you back.³ Each tier keeps the abilities below it:³

• I, Demonsplit: at half health it splits into two demons, Quazii and Typhoeus. Only one of them can be hurt at a time. Kill both and the Demonlord comes back.
• II, Hellion Shield: the boss and its demons take 99% less damage unless you hit them with a Blaze Slayer dagger (such as the Twilight Dagger or Firedust Dagger) set to the shield's attunement: Ashen, Spirit, Auric or Crystal. The shield changes every 8 correct hits. Ferocity doesn't get through.
• II, Fire Pillars: it throws a fireball that becomes a pillar. Hit it 8 times within 7 seconds or everyone fighting the boss dies. The Mithril Coat and Wither Cloak Sword abilities can block this.
• III–IV: it splits twice, at two-thirds and one-third health. Quazii's spinning beam hurts you and heals Quazii if you touch it. From one-third health, fire pits open around you.

Slayer XP and the RNG meter

Only bosses you spawned count for Slayer XP. Levels unlock recipes and permanent stats, and level 8 brings a Blaze-only perk.¹ Tier III and higher kills fill the Blaze RNG meter. Your chosen target drop gets up to three times likelier as it fills and is certain once it's full. Getting it spends its cost from the meter.⁴
