rex infernus nexus forge solver Overview
The rex infernus nexus forge solver is used during the Dravakar Temple riddle step in the Black Ops 7 Zombies Main Quest. After opening Pack-a-Punch, collecting the grapple gun, and completing the crystal-light puzzle, you eventually receive a riddle that determines how the temple switches must be rotated. The solver converts that riddle into a practical switch sequence, allowing you to open the hidden chamber and reach the Nexus Forge.
The quest takes place across the Nexus, four temples, the forest, and several timed objectives. The broad progression is shown below.
| Quest Stage | Main Objective | Important Requirement |
|---|---|---|
| Nexus opening | Activate Pack-a-Punch and collect the grapple gun | Follow the on-screen access route |
| Crystal puzzle | Redirect the astral flame through the temple | Grapple gun and crystal |
| Forest trial | Collect three sections of the Warden’s crossbow | Eat the fruit from the charged tree |
| Dravakar riddle | Match the spoken riddle to the temple switches | Use the Nexus Forge solver |
| Forge reward | Craft the Warden’s Blight Crossbow | Correct switch sequence |

Solo Planning
Keep a clear escape route around the Nexus and avoid starting timed objectives while surrounded by a large train of zombies.
Co-op Roles
Assign one player to read the solver and another to control the temple switches. A third player can manage enemy pressure.
Resource Control
Save grapple gun charges, astral flames, and charged Wonder Weapon ammunition for objectives that require repeated attempts.
Record the riddle before interacting with the switches. The solver is most useful when you can calmly identify the correct riddle number and follow its order.
How to Use the Nexus Forge Solver
The Dravakar Temple puzzle contains four symbols and several movable switches. The spoken riddle identifies a specific combination, but the solution is difficult to calculate manually during a Zombies round. The solver lists the available riddles, explains the symbol directions, and tells you how many times to rotate each switch.
Use this process whenever you reach the temple riddle.
Reach the Dravakar Temple Riddle
After collecting the three crossbow fragments in the forest, return to Dravakar’s Temple. At the back of the temple, approach the blue symbols on the wall and listen to Dravakar’s riddle.
Identify the Riddle Number
Open the solver and select the riddle that matches the wording you heard. The available riddles correspond to different switch combinations, so do not choose a number based only on the first phrase.
Read the Switch Instructions
Check which switch must be used, how many times it should be rotated, and the order of activation. The solver may include the left, right, and bottom switches before the middle pillar is used to lock the result.
Rotate the Symbols
Move between the switches and activate each one exactly as listed. Count every interaction carefully, especially when the left and right switches affect different symbol positions.
Lock the Combination
Interact with the middle pillar after the sequence is complete. A correct solution opens the top of the temple and reveals the secret chamber containing the Nexus Forge.
The solver’s output may vary by riddle. The examples below show the type of information it provides rather than a universal code for every match.
| Riddle Example | Left Switch | Right Switch | Bottom Switch | Final Action |
|---|---|---|---|---|
| Riddle 4 example | 2 rotations | 2 rotations | 0 rotations | Lock with middle switch |
| Riddle 2 example | 3 rotations | 1 rotation | 2 rotations | Lock with middle switch |
When a bottom-switch instruction appears, move behind the main puzzle area and activate the lower switch before returning to the central pillar. The switches can be separated enough that losing track of your position wastes valuable time.
Do not rotate switches randomly after selecting the riddle. If the sequence is lost, slow down, compare the current symbols with the solver, and restart the input methodically.
After the temple opens, use the grapple gun to reach the upper secret room. The Forge is found inside this chamber and allows you to craft the Warden’s Blight Crossbow once the required crossbow sections have been collected.
Crossbow Parts and Temple Trial Setup
The Forge is only one part of the Wonder Weapon quest. You must first charge the tree, enter the forest, and recover three pieces of the Warden’s crossbow. Each piece comes from a dead body in a different forest location.
| Forest Location | Access Method | Quest Item |
|---|---|---|
| Central rock | Interact with the body after the cutscene | Crossbow section |
| Broken building | Punch through the floor | Crossbow section |
| Rear cave entrance | Search the body near the cave | Crossbow section |
Stand near the charged tree to provide life essence. After enough essence has been transferred, fruit appears. Eating the fruit teleports you to the forest. Search all three bodies and pick up every crossbow fragment before leaving the area.
The remaining temple trials prepare the map for the final confrontation. One early example is the Vetherion Temple block puzzle, which requires four blocks to be placed in a fixed order.
| Block Placement | Required Symbol |
|---|---|
| First | Fire |
| Second | Hand |
| Third | Leaf |
| Fourth | Waves or water |
Once the blocks are inserted, move them across the wall using the central orb. The puzzle requires several transfers and stack changes, so complete each placement in sequence. If the arrangement fails, collect the blocks again during the next round and repeat the order.
The grapple gun also receives an upgrade during the quest. Return to the house and fire a ball from Paradox Junction through the rubble. A symbol appears on the wall. Repeat the round-flip process three more times, recording each symbol and its location. At the beginning of the next Xfill round, shoot the symbols in the order they appeared.
Pack-a-Punched Wonder Weapon ammunition is required for some barricades and reflector objectives. Upgrade the weapon before attempting the later temple stages.
After the Xfill objective, eliminate the High Value Target and return to the house. On the second floor, use a charged Wonder Weapon shot to break the barricade and collect the eye. Use the phone downstairs to return to the Nexus, then place the eye at the grapple location you want to upgrade. Only that grapple point receives the upgrade, so choose a location that supports your preferred movement route.
Reconstruct the Nexus and Cleanse the Temples
Once the grapple gun is upgraded and the Vetherion trial has been completed, begin reconstructing the Nexus. Use the upgraded grapple points at the bottom of the Nexus to remove panels from both sides of the wall. Repeat the process at the three ground monoliths to expose the gears.
Bring essence to the center, crank the generator, and carry purple fire to the revealed machinery. Clear the webs from the gears on both sides. Capture another orb, charge the generators again, then activate the lever at the lower section to overdrive the system. Interact with a monolith quickly afterward to begin moving the three stones.
| Nexus Task | Action | Result |
|---|---|---|
| Remove wall panels | Grapple both sides of the lower Nexus | Reveal gears |
| Clear the gears | Carry purple fire to the machinery | Prepare the generator |
| Charge the system | Bring essence and crank the generator | Enable overdrive |
| Overdrive | Activate the lower lever | Allow monolith movement |
| Align the stones | Move all three monoliths before a temple | Start cleansing |
Each temple requires a corrupted item, a zombie symbol interaction, a reflector puzzle, and a final orb-and-rain sequence. The item and reflector position differ by temple.
| Temple | Corrupted Item | Main Reflector Condition |
|---|---|---|
| Dravakar | Hammer piece | Kill a zombie over the pressure plate tile with a frag grenade |
| Caltheras | Random item from temple orbs | Stand on the plate while looking toward the Mystery Box |
| Nixara | Ancient scroll | Go prone on the plate and flip the round |
| Vetherion | Woven sash | Jump on the pressure plate 30 uninterrupted times |
After cleansing the item in the temple fire pit, lead a zombie toward the matching Titan Trap. The zombie displays a symbol and colored smoke. Match that symbol and smoke color to the correct shackle, then allow the Titan Trap to crush the zombie. This removes one of the restraints.
The reflector step follows. Use a charged Wonder Weapon shot to raise the reflector, then redirect the beam to the required corner of the temple. The placement is sensitive, so make small adjustments until the beam reaches the intended location. Charge the reflector with zombie souls to reveal the temple head. Destroy the head with another charged shot, defeat the spawned ghosts, and break the head again.
Many reflector and zombie-symbol steps are vulnerable to enemy pressure. Use decoys, Ether Shroud, or a controlled zombie when the objective requires standing still.
The final cleansing action generally involves moving an orb beneath the exterior statue, launching it upward with the Wonder Weapon, causing rain through the temple pool, and throwing purple fire at the statue’s forehead. Complete the temples in an order that keeps your monolith movement manageable.
Warden Boss Fight and Completion Checklist
With all four temples cleansed, prepare for the Warden encounter at the bottom of the Nexus generator. Players stand on the blue portals to enter the arena. The Warden is a fast spider-scorpion hybrid that can deal heavy damage, stun players, and knock them from the arena.
Mobility is central to the fight. Refresh grapple access at the fountains on either side of the arena and keep moving when the Warden focuses on you. Floating skulls beside the boss can be destroyed with the Wonder Weapon to expose a stronger critical point near the top of its tail.
| Boss Phase | Primary Threat | Recommended Response |
|---|---|---|
| Phase One | Fast attacks and stuns | Use grapple fountains and target floating skulls |
| Intermission | Warden drains Ava | Destroy the ghosts around the arena |
| Phase Two | Skull armor, ghosts, and rising tails | Clear skulls, watch the arena floor, keep moving |
| Prison sequence | Timed survival section | Run and survive instead of forcing kills |
| Phase Three | Combined tail lightning attack | Destroy tails or use a timed arena escape |
During the first phase, focus on the skulls rather than wasting ammunition against protected areas. When the critical point opens, use your highest-damage weapon and Wonder Weapon attacks. During the next phase, ghosts may act as armor if skulls are not visible, so scan the arena before assuming the boss is vulnerable.
The prison sequence is a survival check. You do not need to eliminate every enemy; prioritize movement and wait for the section to end. Later phases introduce more dangerous tail attacks, including a lightning pattern that can cover the center of the arena.
