Defeat Anime RNG Merging Guide: Fuse Rules and Copy Requirements
See the Fuse screen and its same-level duplicate rule in Defeat Anime RNG, then check selected-unit costs, results, and mutations before merging.
What is confirmed about merging?
The developer explicitly lists merging anime units to level them up as part of the game loop. A public gameplay recording also shows the actual Fuse interface and its instruction:
Level up units by sacrificing duplicate units of the same level.
This adds a concrete requirement: look for duplicates at the same level when preparing a fuse. The recording does not establish how many copies every selected recipe needs or how much each new level adds to damage.

What does the 0/1 Copies counter mean here?
In this frame, the first unit slot is empty, the middle slot says Click to add, and the counter reads 0/1 Copies. The result slot is also empty. No particular unit or level has been selected, and the screenshot does not show a completed fuse or an inventory deduction.
| Visible in the recording | What it establishes |
|---|---|
| Fuse units to make them stronger! | The action is named Fuse in this interface |
| Sacrificing duplicate units of the same level | The menu describes consuming matching-level duplicates for leveling |
| Empty selection and 0/1 Copies | The default counter before selecting a recipe; not a universal cost table |
| Empty result slot | This frame does not establish the output level or retained modifiers |
Count the selected unit and any sacrifice copies separately. A default counter alone does not prove that every fuse takes two units, three units, or a fixed number at every level. It also does not establish a coin charge or whether the action is free.
A selected Qiora preview
Around 19:46 in the same recording, both input slots show Qiora, followed by a Qiora result preview and a green Fuse button. This provides a concrete example of choosing a unit together with a duplicate, rather than relying on the empty counter.

The picture shows a preview, not proof of the final inventory deduction. Do not generalize it into a cost for all levels, assume a particular mutation survives, or infer that there is no additional currency cost. Record the selected copies and the result in your own game before confirming.
Use the live merge screen as your reference for a particular action. A guide can help you compare the choices; it should not replace the requirements shown for the units you actually own.
If you have only just joined, the beginner guide places this step in the wider roll, fight, and zone progression loop.
What should you inspect before confirming a merge?
Pause at the last screen before confirmation and check these items:
| Check | What you want to know |
|---|---|
| Selected units | Which exact copies are involved? Read names, levels, and extra labels |
| Required amount | How many copies or other resources does this particular action request? |
| Result preview | Which unit and level will the action produce, if shown? |
| Resource cost | Does it use a resource you need for your next zone goal? |
| Special properties | Does the result explicitly retain or change a mutation or other modifier? |
| Confirmation wording | What does the game say will be consumed or changed? |
If the result is not clear, stop and inspect further. That is especially useful when the selection includes the only copy of a unit you currently rely on.
The mutations guide explains why a mutated unit should be identified separately from an ordinary copy. We have not verified an inheritance rule, so an attractive result icon alone is not a reason to assume its modifier will carry over.
How should you compare a merge with another upgrade?
Choose the obstacle you are trying to solve first. If a fight is stopping progress, ask whether the displayed result improves a unit you will actually use there. If a zone gate is the obstacle, compare the resource cost with the gate’s current requirement.
That leads to a simple decision:
- Write down the next goal, such as clearing the current fight or meeting a visible gate requirement.
- Inspect the merge’s displayed requirements and result.
- Compare any shared resource cost with that goal.
- Proceed only when the result and tradeoff are clear enough for you.
For a reported early access milestone, see Death Castle. This comparison does not assume its price is fixed or that its currency is also used by merging.
How can you tell whether a unit change helped?
Keep the comparison as similar as the game allows. Record the unit’s before-and-after level and displayed stats, then attempt the same encounter with the same other conditions.
Change one thing at a time. If you merge a unit, change the rest of your setup, and activate a potion together, a better result will not tell you which change mattered.
Useful observations include whether the fight cleared, how long it took, or where an endless run ended. Only record values the game actually shows or that you directly time; do not convert a stat into damage per second without knowing its meaning. The bosses and endless guide expands this comparison method.
What should you avoid assuming?
Rarity, level, and modifiers describe different parts of a unit. A name or rarity label alone does not establish that one of your copies is better for your current obstacle.
This guide does not prescribe a universal merge ratio, a maximum level, a damage-per-level formula, or a list of expendable units. Those need a current, verified dataset. You can still make a useful decision by reading the actual action and comparing the result against your current need.

The same-level duplicate rule above is observed in another creator’s recording. The comparison procedure is our editorial advice. Selected-unit recipes, additional resource costs, mutation inheritance, and level formulas still need specific evidence; this page does not claim that we completed a fuse ourselves.
