The Necrofluid Gauntlet was built for Ashes of the Damned, but it also has a hidden route into Rex Infernus, the final map in Black Ops 7 Zombies. You don’t get it from a puzzle or a boss fight. You get it by feeding Dravakar’s Forge one Pack-a-Punched weapon from every standard weapon class. Once the eighth offering lands, the forge gives you the gauntlet already upgraded.
Quick answer: First craft Warden’s Blight. At Dravakar’s Forge, offer a weapon from each of the eight classes, with every weapon upgraded to Pack-a-Punch Tier 1 or higher. You may make only one offering in a round.

Necrofluid Gauntlet requirements in Rex Infernus
The forge stays inactive until you have finished the map’s own Wonder Weapon quest. Picking up Warden’s Blight, the dual crossbows you assemble on Dravakar’s anvil, switches the forge on. Every other rule follows from there.
- Warden’s Blight must be obtained first. Doing so activates Dravakar’s Forge.
- The forge sits in Dravakar Inner Sanctum, which you reach with the Void Claw grapple.
- A weapon is eligible only after reaching Pack-a-Punch Tier 1 or above.
- The forge accepts one sacrifice per round, so the ritual takes at least eight rounds.
- Order doesn’t matter. Each of the eight classes just has to be offered once.
Wonder Weapons, melee weapons, and Special weapons don’t count toward the ritual, so leave Warden’s Blight and your knife out of it.

The forge checks the class, not the specific gun. Any weapon in the right category works as long as it has been upgraded. The picks below are the quickest to grab on Rex Infernus, and most of them are wall-buys.
| Weapon type | Fastest pick | Where to get it |
|---|---|---|
| Pistol | Coda 9 | Her House, or Mystery Box |
| SMG | Ryden 45k | West Nexus Forge, by Nyxara’s Passage |
| LMG | MK.78 | Nexus Core, beneath Nexus Forge |
| Shotgun | Echo 12 | Nyxara’s Passage, north of Stamin-Up |
| Sniper Rifle | VS Recon | Nyxara’s Sanctuary south wall, past the Arsenal |
| Marksman Rifle | M8A1 | Veytharion’s Passage, near Vulture Aid |
| Assault Rifle | Peacekeeper Mk1 | Nyxara Entrance, north side past the door |
| Launcher | A.R.C. M1 or AAROW 109 | Mystery Box only |
The launcher is the one slot you can’t buy off a wall. Both options come only from the Mystery Box, and the box is random. Spin it whenever you have spare Essence while you work through the other seven classes, so you aren’t stuck hunting for a launcher at the end with a full ritual waiting on it.

How to sacrifice weapons at Dravakar’s Forge

Because you’re capped at one offering per round, it helps to have the next upgraded weapon ready before the round ends. That way you can sacrifice it right away and avoid wasting a round.
How you know the Necrofluid Gauntlet ritual worked
When the eighth class is accepted, Dominance of Dravakar appears on the forge’s anvil. That’s the Necrofluid Gauntlet in its Pack-a-Punch Tier 1 form. Interact with it to pick it up. You don’t have to fight anything or solve anything else after the last sacrifice.
It plays the same way it does in Ashes of the Damned. It fires necrofluid spikes that stick in enemies, and you can recall them to hit again and restore health. The upgraded version adds an alternate attack that detonates the spikes for area damage and extra healing. That combination makes high rounds, and another attempt at the Rex Infernus main quest, much more forgiving.
