How to Get Rex Infernus Wonder Weapon in BO7 Zombies

The Wonder Weapon on Rex Infernus is Warden’s Blight, a dual-wield crossbow you craft through the map’s corruption quest. Rex Infernus is the map, Warden’s Blight is the weapon, and the two get mixed up constantly because the crossbow leaked from a cosmetic bundle before launch under names like “Golden Claw”.

What the Rex Infernus Wonder Weapon Is

Warden’s Blight is a dual crossbow that unloads arrows from the left and right hand. Pack-a-Punch it and the game renames it, adding an ether bolt and a charged cyclone shot that sucks zombies in before it detonates. The upgraded variant of the Warden’s Blight reads as “Seelve and Cashier”.

Get to Pack-a-Punch First

You cannot start the crossbow build until Pack-a-Punch is live, and that is its own short quest. Hold out in “Her House” for a few rounds, answer the ringing phone to open the exit and spawn a teleporter, then place the World Seed at the Nexus Forge. That releases two Dread Skulls. Take down each skull inside its Shadowsmith temple to light a brazier from the cauldron, then turn both crank wheels to lower the forge and switch Pack-a-Punch on.

The Void Claw grapple sits behind a newly opened doorway at the Nexus Forge the moment Pack-a-Punch activates. Grab it. You need the grapple for the crossbow steps, but again, it is the tool, not the weapon.

How to Build Warden’s Blight, Step by Step

This is the route we ran end to end. The wider community was still finalizing the exact universal order at the time of writing, so if a step gates differently in your lobby, that is why. The sequence itself held up for us.

1. Corrupt the forge. Pull the purple orb into Pack-a-Punch and crank it. Done right, the cauldrons light with purple flame.

2. Get the crystal. Head to Dravakar’s temple and break the marked wall with an explosive. PhD Flopper works, so does a grenade. Take the crystal from inside.

3. Solve the eye puzzle. Place the crystal on the right wall in Nyxara’s temple. Go back and interact with the purple flame, carry it to the eye at the back of Nyxara’s temple, throw the fire at the eye, and complete the laser puzzle with your grapple. The door opens on the blue beam.

4. Charge the vine. Move to the floating orb through the open door. You get stunned, drop through the floor into a hidden room, and reach the vine. It siphons your health while it charges, so top up before you commit.

5. Collect the three parts. A fruit spawns around round 8. Interact with it to teleport to a forest, then find three bodies and take a part from each. One is hidden under a board you have to knife to reveal. Sprint backwards as you grab them to cancel the cutscene and pick them up instantly.

6. Enter the lever code. Back at Dravakar’s temple, interact with the blue-symbol wall for a riddle. Four riddles map to four lever orders across three levers, then you pull the center lever to confirm. Get it right and you hear dialogue with a screen flash. Get it wrong and you wait until next round.

Rex Infernus lever code solver

Listen for the spoken riddle, subtitles show it too, then pick it below and match the levers. Reset them to their starting position first.

1 Hear your riddle

The blue-symbol wall speaks your riddle when you interact with it in Dravakar’s temple. It plays as audio, so turn on subtitles to read it, or listen closely. It is randomized per lobby, so match the line you hear below.

2 Pick it, then pull the levers

Levers not at the start? The counts assume every pillar faces the center. If you already pulled some, fail the input once to reset, then try again next round.

Enter the code correctly and the center pillar sinks into the floor, opening the roof above it. That opening is your way up, so head into the ceiling to reach the chamber where Warden’s Blight is crafted.

7. Craft the weapon. Grab a grapple hook, grapple up into the opening, and interact with the anvil ringed in blue flame. Warden’s Blight appears there.

Is Warden’s Blight Worth It

As a weapon, it hits hard. At triple Pack-a-Punch one creator clocked charged shots around 51,000 damage, and the cyclone pull makes it strong for thinning big rounds. As a quest, it is a long one, and the community reaction has been mixed.

Honestly, a C+/B- for me. The WW quest is a huge slog and it’s not a particularly great WW anyways. Quest reminded me of the staff upgrades step where 99.99999% of people are just going to look up the correct combination.

u/margwa_, r/CODZombies

That is the honest read. If you love a long build, Warden’s Blight is a satisfying payoff. If you just want the crossbow, follow this checklist and skip the puzzle-solving, because most players are looking it up anyway.
