Night Swarm How to Fuse

Turning two simple relics into one powerhouse is what separates a good run from a broken one. Fusion unlocks massive upgrades that make bosses melt and builds click together perfectly. Here’s the full breakdown on how to fuse relics the right way every time.
How Fusion Actually Works
Fusion happens when you level two specific Active Relics to level 10 during a single run. Once both relics hit level 10, the fuse option appears automatically. If that relic pair is a valid recipe, they merge into a stronger Fusible Relic.
Recipes are fixed, so you can’t guess your way into random fusions. Each one follows a real combination, like Blood Axe plus Ice Orb becoming Axe Shatter.
Leveling Relics For Fusion
Early on, focus on building around your two chosen relics. Always select upgrades for them when the relic level-up screen appears. Fusion won’t start until both are exactly level 10, and removing or swapping one out resets progress. Keep both in your Active Relic slots the whole time.
Choosing The Right Relic Pair
Each Fusible Relic comes from a locked pairing. The order you grab them doesn’t matter, but both must exist in your active loadout before fusing. If one is missing or replaced, the fuse option won’t show up.
Some pairs work better for damage stacking, others for status effects or crowd control. Once you know the recipes, you can plan your builds around guaranteed fusions instead of waiting on luck.
What Happens After Fusion
When the fusion completes, the two base relics vanish and you receive the upgraded Fusible Relic in their place. This clears an extra slot, allowing you to pick up another relic and start a second fusion later in the same run. High-level players often chain multiple fusions for endgame builds.
Common Fusion Issues
Fusion won’t trigger if:
One relic is below level 10
You’ve swapped or removed one of the relics
The relic pair isn’t part of a real recipe
You’re using Passive Relics or Artifacts instead of Active Relics
Easy Fusion Tips
Pick your target relic pair early to increase spawn chances
Pour all upgrades into your two chosen relics until level 10
Fuse quickly to free space for more relic options
Use banish to thin out junk relics and clean up your pool
Save secondary relics until your first fusion finishes
Final Blurb
Fusing relics in Night Swarm turns every run into a custom power fantasy. Learn the right recipes, feed them levels, and you’ll be clearing waves like a vampire god in no time.
