rex infernus astral flame: Step-by-Step Quest Guide

The rex infernus astral flame objective is one of the key progression steps in the Rex Infernus Main Quest. After activating Pack-a-Punch, the crew must upgrade the Usurped Flame into Astral Fire, then use it to unlock a hidden route through Nyxara’s Sanctuary. This path eventually leads to the parts needed to assemble the Warden’s Blight Crossbow.

Rex Infernus launched with Season 05 Reloaded on August 20, 2026, serving as the final Round-Based Zombies map in Black Ops 7. The quest focuses on cleansing the Shadowsmiths’ places of power, reaching the Warden’s inner sanctum, and confronting the force behind the collapsing reality.

Before Astral Fire can be used, the map’s opening sequence must be completed. Start in the abandoned house and survive the initial holdout objective. The phone will ring after several minutes, and answering it triggers a short scene that opens the exterior route.

Travel through the portal to the Nexus Forge, where the World Seed can be placed. This summons two red flying skulls called Dread Skulls. Each skull leads to a different location and must be destroyed to continue the forge sequence.

The first Dread Skull takes you toward the area associated with the Usurped Flame. Use the flame to seize the required energy and return it to the brazier at the Nexus Forge. A fireball attack activates the brazier. Repeat the process for the second skull, which leads toward Caltheris’ Main Chamber.

Once both braziers are lit, rotate the Crank Wheels. The forge will glow with runes, lower beneath the ground, and create a staircase around the platform. Pack-a-Punch becomes active at the end of this sequence.

After that, search for a floating purple orb. Use the grapple to grab it and carry it back to the Nexus Forge. Place the orb into the forge and activate the mechanism again. The flame changes from its original state to a blue flame called Astral Fire.

The flame upgrade and the crystal collection can be handled in the same preparation route. From inside Dravakar’s Main Chamber, look above the entrance. Grapple or wall-jump to the upper platform, then break the wall section on the right with a grenade or another explosive. The Purple Crystal is behind the damaged section.

Take Astral Fire to Nyxara’s Sanctuary. At the end of the temple, locate the large eye and shoot it with the blue flame. This starts a light-beam puzzle involving several purple crystals positioned around the room.

The crystals can be rotated with the grapple. Your objective is to redirect the beam from one crystal to the next until it reaches the location where a crystal is missing. Place the Purple Crystal from Dravakar’s Main Chamber into that empty slot, then continue rotating the remaining crystals until the beam reaches its final destination.

The exact crystal arrangement can vary between matches. There is no single universal combination to copy. Instead, listen to Dravakar’s clues and inspect the visible beam path. Adjust one crystal at a time, then confirm whether the beam reaches the next target before changing another position.

When the alignment is correct, a hidden room opens and reveals a strange tree. Interact with its roots and sacrifice some health to feed it. After the tree receives enough health, it grows a fruit. Eating the fruit transports you to the Silent Area, a dark forest containing the Warden’s Blight parts.

The Silent Area does not provide all three Warden’s Blight parts during one visit. You can collect only one part per visit, so plan for three separate trips. After collecting a part, leave the area, advance to the next round, return to the tree, and eat another fruit to reenter.

The parts are located near corpses placed around recognizable landmarks in the forest.

For the burned cabin location, a normal melee attack may not trigger the plank. If it does not react, use Melee Macchiato and strike the glowing wooden section again.

After collecting all three parts, return to Dravakar’s Main Chamber. A pillar puzzle must be solved before the weapon can be assembled. The symbols include the Star, Moon, Runner, and Galaxy, and the solution is randomized between matches.

Read the writing on the wall and listen to Dravakar’s riddle. The clues describe how the symbols relate to one another. For example, if the clue says that the Star follows the Moon, rotate the Star pillar so it points toward the Moon. Apply the same logic to the remaining symbols.

Once every pillar faces the correct direction, an opening appears above Dravakar’s chamber. Grapple through the hole in the ceiling and interact with the build location to assemble the Warden’s Blight Crossbow.

Rex Infernus introduces two spider-themed enemies: Deathspinners and the Web Mother. Deathspinners are fast opponents that can fire web projectiles capable of slowing players. Prioritize them when several spawn together, especially if the web effect limits your movement.

The Web Mother is the map’s new Elite enemy. It can scream, lunge at players, cover areas with damaging webbing, and cocoon zombies. Maintain open space when fighting it, and avoid allowing web effects to block your escape route.

The map also features the Titan Trap, a large environmental trap that summons a massive force to pound the ground. It pulls nearby zombies into the attack, but players can also be damaged if they stand too close during activation.

Widow’s Wine returns as a Perk-a-Cola in Season 05 Reloaded. Its Major Augments include Widow’s Bite, Hatchling, Web Spinner, and Tangled Web. Minor Augments include Haste, The Wide Web, Golden Orb Silk, and Sticky Grenade.

The new Fully Packed Ultra GobbleGum can instantly upgrade the weapon being held to Pack-a-Punch Level III. It may help conserve Essence during early Main Quest attempts, particularly when preparing for later quest stages.

Completing the Rex Infernus Main Quest provides the following confirmed rewards:

The TR2 Marksman Rifle and Olympia Shotgun also join the Mystery Box as Ultra-Rarity legacy weapons. For the map’s Cursed Mode, expect reduced guidance, limited HUD information, and a pistol-only starting condition. Finishing the standard quest first is the more practical route before attempting that challenge.
