Rather than being summoned one at a time like normal death spawns, the Nechryarch summons 3 chaotic spawns immediately when it calls for them. The chaotic spawns also cover all three forms of the combat triangle; one uses melee, another uses magic, and the other one uses range.
These chaotic spawns are more accurate than their normal variants and have a higher max hit of 7. However unlike their normal variants, their attacks can be blocked with protection prayers, though the best way to deal with the chaotic spawns in single-way areas is to run away until they lose interest, as they will not target the player again when they attack the Nechryarch. In multi-way areas, they can be killed with burst/barrage spells instead.
Once the Nechryarch dies, any chaotic death spawns they summoned will also despawn.
- Prior to an update on 30 March 2017, chaotic death spawn shared the same appearance as their normal counterpart. This was added to make them more easily identifiable; the ranged spawn wears a green torso, the magic spawn wears magic robes, and the melee spawn has its hood removed.
