Nexus & Catalysts
Catalysts as furnace fuel
Place a finished Nexus Catalyst or Stable Nexus Catalyst in a furnace's fuel slot to burn it. This consumes the item as fuel instead of activating a Nexus.

Nexus Catalyst: 10 ticks of burn time (0.5 seconds at 20 TPS).

Stable Nexus Catalyst: 16 ticks of burn time (0.8 seconds at 20 TPS).

Versus Catalyst
Shapeless: 1 Nexus Catalyst + 1 Damping Agent → 1 Versus Catalyst. Item ID: invmod:versus_catalyst. Make the Nexus Catalyst from smelted Catalyst Mixture; make the Damping Agent from Rift Flux and two lapis lazuli.
Insert it yourself through an inactive Core's Catalyst slot to start an owner-bound battle. Each opponent needs their own Core in the same dimension. An additional catalyst can recruit an unbound living mob. See the Versus guide for activation limits, mob purchases and match resets. This branch does not use Strong Nexus Catalyst + lapis for this recipe.
Player Nexus Catalyst
Shapeless: 1 Strong Nexus Catalyst + 1 Emerald → 1 Player Nexus Catalyst.
Item ID: invmod:player_nexus_catalyst.
Craft the ingredients anywhere in a crafting grid. Obtain the Strong Nexus Catalyst by crafting or Nexus processing at level 10+. Insert the finished Player Nexus Catalyst into the Nexus input slot to become the invasion target. The Core disappears and the invasion follows you; see activation, rewards, and survival rules.

To carry an existing opposing-team battle, activate your Versus Core first, then transfer it as its owner. Color, unlocks, combat/economic skills and Auto Buy are retained; this recipe alone does not activate Versus.
Strong Nexus Catalyst from Rift Flux
As an alternative to crafting a Nexus Catalyst with a Phase Crystal, a developed Nexus can turn 1 Rift Flux into 1 Strong Nexus Catalyst. The Nexus Core is the workstation and is not consumed.
How to process it
- Open the Nexus and check its displayed Nexus level. Processing requires level 10 or higher.
- Empty the output slot, then place Rift Flux in the input slot (the same slot used for catalysts).
- Allow about 12 seconds at 20 ticks per second for a fresh processing cycle. One Rift Flux is consumed when the finished catalyst appears in the output slot.
- Collect the Strong Nexus Catalyst. If more Rift Flux remains in the input, another cycle can complete once the output is empty again.
Level and operating conditions
Nexus level is stored separately from the current wave and the continuous-mode power level. Normal wave progression raises it when a new wave exceeds the stored level; simply starting Strong mode at wave 10 does not itself set Nexus level to 10. Check the level in the Nexus screen instead of relying on the wave HUD.
The process also works while the Nexus is stopped or the invasion is paused, as long as the Nexus is still being ticked by the server. A fresh Rift Flux cycle needs 240 inventory ticks at level 10 or above. Emptying the input resets processing progress.
Use the result to start a Strong invasion, or insert it into an active Nexus to skip 10 waves. Leaving it in the output does not activate it. Rift Flux also has resource conversions and equipment recipes.

Rift Flux & Conversions
The grids below are crafting recipes. The Nexus Exchange tab has its own rates and supports selling complete packages back, Gamble and Auto Buy. For example, 1 Flux crafts 4 iron ingots but buys 8 in Exchange.
For passive production, see current wave-based Flux rates, hopper extraction and overflow. A stopped or paused Nexus does not advance this counter.
Using JEI? The Rift Flux Generation category shows the Nexus production process, how to find it, and why the Core is not consumed.
Finding invaders with food
Small Remnants and Rift Flux are also edible. Eating either restores 1 food point (half a hunger icon) and applies Glowing to loaded, living IM combatants in the same dimension. Their outlines help you spot invaders through walls or underground when finishing a wave.
Small Remnants
Glowing lasts 60 seconds. Item ID: invmod:small_remnants.
Rift Flux
Glowing lasts 10 minutes. Item ID: invmod:rift_flux.
Use at full hunger
Both items can be eaten with a completely full hunger bar. You do not need to sprint or take damage first. Hold the item and hold Use (right-click by default) until eating finishes. In Survival, one item is consumed even at full hunger; the Glowing effect still applies. The normal eating action must finish: merely clicking or cancelling the action does not highlight enemies.
At less than full hunger, either item restores 1 food point with a 0.1 saturation modifier. At full hunger it cannot raise the food bar beyond its normal maximum. These items reveal invaders; they do not directly heal you or damage the highlighted mobs.
How to use it
- Keep a Small Remnant from defeated invaders, or craft Rift Flux using nine Small Remnants.
- Hold the item and hold Use until you finish eating, including at full hunger. One item is consumed in Survival.
- Look for glowing outlines and follow them to the remaining attackers. Glowing reveals their position; you still need to defeat them.
The effect reaches registered IM combatants throughout the same server dimension, without a distance or Nexus-ownership restriction. It affects those loaded when you finish eating; it does not load distant chunks or automatically mark enemies that spawn later. Ordinary mobs outside the IM combatant registry and mobs in other dimensions are unaffected. In Versus, the outline uses each mob's Nexus team color; eating does not change ownership and can reveal both armies.
Equipment & Tools
Learn about the Infused Sword's attacks without durability loss and how to recharge its ability through damage and time the Searing Bow’s empowered shot.
Both Nexus tools adjust a placed Core from 8 to 1024 blocks, in 8-block steps when its wave spawner is inactive. The temporary recovery search leaves that setting unchanged; Versus hides its menu label. See Nexus radius controls and Material Probe block-strength checks for tool usage. The Engineer Hammer is a test tool without a crafting recipe in the 26.3 / NeoForge branch.
Use for wolf conversion or recalling your IM Wolf to its active Nexus. Recall consumes one bone only on success.
Frozen equipment & Nexus Pickaxe
Recipes verified for Minecraft 26.3 / NeoForge. Each recipe below produces one item. Frozen Bone (invmod:frozen_bone) comes from Frost Skeleton T1/T2; Frozen String (invmod:frozen_string) and Frozen Eye (invmod:frozen_eye) come from Jumping Frost Spiders.
Frozen Bone
Frozen String
Frozen Eye- Frozen Bow: shaped, 3 Frozen Bones in the bow's curved frame and 3 Frozen Strings in the right column.
- Frozen Arrow: shaped 2×2 diagonal, Frozen Eye at top-right and Frozen Bone at bottom-left. Produces 1 arrow.
- Nexus Pickaxe: Netherite Pickaxe in the center, Rift Flux in all eight surrounding slots.
Traps & Dampening
Damping Agents are consumed in the active Nexus input slot. See mode-specific pauses and delayed Stable nights, including effects on production.
Nexus process conditions
Open the placed Nexus Core and use its input/catalyst slot for the ingredient. Finished items share the output slot with generated Rift Flux. The Core is the workstation and is not consumed. These inventory processes work while stopped or paused, provided the server continues ticking the Core; a Player Nexus has no Core inventory after transfer.

1 Empty Trap → 1 Rift Trap
No additional Rift Flux ingredient and no minimum Nexus level. See charging steps and timing.
| Process | Operating conditions | Required output |
|---|---|---|
| Empty Trap → Rift Trap | About 6.75 seconds in a non-stopped mode; about 60 seconds while stopped, from zero progress at 20 TPS. | Empty, or an existing Rift Trap stack with room for another trap. |
| Rift Flux → Strong Nexus Catalyst | Nexus level 10+ to advance a fresh cycle; about 12 seconds at 20 TPS, including while stopped or paused. | Completely empty. An existing catalyst stack also blocks delivery. |
| Passive Rift Flux generation | Running mode and generation cycle determine progress; stopped or paused invasions do not generate new Flux. | Empty or a matching stack with room stores output; excess drops above the Core. Auto Buy changes the produced item. |
A blocked output holds a completed input process; the input item is consumed only when the result is delivered. Collect the output regularly, especially when an active Nexus produces Flux that blocks your trap or catalyst. Emptying the input resets the shared processing progress. Times above assume a fresh cycle and 20 TPS; server lag increases real waiting time.
