Diablo Immortal Hellspawn’s Bane: How It Works and Rewards

Diablo Immortal Hellspawn’s Bane-themed version of Survivor’s Bane available during Hellborne Horrors from September 29, 2026 until November 1. It adds six Spawn-inspired skills and a timed trip to Hell to fight Heap.

The six confirmed powers are Hell Chains, K7-Leetha Cloak, Necroplasm, Hell Fire, Spiritual Manipulation and Agony. Hellspawn’s Bane also connects to Hellspawn’s Vengeance weekly objectives, allowing the activity to contribute Vengeance Marks toward the main collaboration reward track.

Fight waves of demons and collect skill orbs during the run. The collaboration version adds its own Spawn powers to the Survivor’s Bane formula. A new timer is active as well. When it expires, the game teleports you to Hell for the Heap encounter before returning you to the original area.

Hell Chains lashes a cone in front of the player. K7-Leetha Cloak activates a regenerating cloak that continuously damages nearby enemies. Necroplasm rapidly fires three projectiles forward. Hell Fire creates a short-lived damaging Hell Rift. Spiritual Manipulation charges before rooting and damaging enemies in its area. Agony throws a spinning axe that pierces enemies.

Diablo Immortal Hellspawn’s Bane: How the Heap encounter works

When the new timer runs out, you are transported to Hell and face Heap, a Spawn creature Blizzard describes as opposing both Heaven and Hell. Defeat Heap and the game returns you to your previous location. A special combat orb then drops and grants a temporary buff. Blizzard lists no hidden summon item or separate Heap quest.

Choosing Spawn skills

The confirmed abilities cover different jobs. Hell Chains supplies frontal area damage, K7-Leetha Cloak handles enemies surrounding you, Hell Fire controls a fixed zone, Spiritual Manipulation adds a root, Agony pierces groups and Necroplasm fires forward projectiles. The best choice depends on the upgrades offered during that particular run rather than a fixed official tier list.

Vengeance Marks and rewards

Blizzard names Diablo Immortal Hellspawn’s Bane as an activity tied to Hellspawn’s Vengeance weekly objectives. Completing the relevant objectives contributes Vengeance Marks toward rewards including 10 free weapon skins, six emotes, the Hellspawned Dominion Avatar Frame, Necroplasmic Totem, Legendary Crests, Legendary Gear and Set Items.

When Hellspawn’s Bane ends

The Spawn version of Survivor’s Bane is part of the limited event ending November 1 at 2:59 a.m. PDT. Check weekly Vengeance objectives throughout the collaboration instead of assuming a single run completes the wider reward track. Heap and the six Spawn skills are features of this special event version.

Important event context

Hellspawn’s Bane is mechanically distinct from The Eighth Circle. Bane is the wave-survival activity with skill pickups and the Heap interruption, while The Eighth Circle is the Malebolgia group boss challenge. Both can contribute to the same Vengeance progression, but their moment-to-moment objectives are different.

What the official notes confirm

Diablo Immortal Hellspawn’s Bane is covered by Blizzard’s final September 2026 Spawn collaboration notes. The guide above sticks to the acquisition routes, event dates and mechanics Blizzard actually published. Where the official notes do not provide an exact tier threshold, drop guarantee or attack rotation, the article leaves that detail to the live game instead of filling the gap with an unsupported value.

What changes from regular Survivor’s Bane

The Spawn version keeps the familiar idea of surviving demon waves while collecting skill orbs, but the collaboration changes the available powers and adds the timed Heap interruption. That timer is important because the trip to Hell happens during the run rather than being presented as a separate selectable boss activity. After Heap dies, returning to the previous location lets the run continue with the temporary combat-orb benefit. The official description does not say that defeating Heap ends Hellspawn’s Bane immediately. Treat Heap as a special encounter inside the mode, while Malebolgia remains the separate boss associated with The Eighth Circle.
