EX-MOD Customisation
EX-MODs are customisation effects attached to a specific weapon. Weapon fusion combines two weapons of the same type, pooling their EX-MODs. The cap is four EX-MODs per weapon. Specific effect names, costs, probabilities, and optimal combinations are NOT_CONFIRMED by official sources. Use the fusion checklist below to record your own test observations.
What Is an EX-MOD?
EX-MODs are customisation effects attached to a specific weapon. Each EX-MOD modifies how that weapon performs. The official demo guide describes EX-MODs as a core part of Echoes of Aincrad's build system alongside Growth Points.
Fusion Rules
Same Weapon Type
Both source weapons must be the same type (e.g. Sword and Shield + Sword and Shield). Cross-type fusion is NOT_CONFIRMED in official sources.
Four EX-MOD Cap
The fused weapon holds up to four EX-MODs. EX-MODs beyond four from the source weapons do not carry over.
Result Keeps Weapon Type
A fused Sword and Shield remains a Sword and Shield. The weapon type of the sources is preserved in the result.

The smithy is where weapon customisation and fusion takes place. This is confirmed in the official guide.
Fusion requires two weapons of the same type. Cross-type fusion is not confirmed. Record the type and any EX-MODs on each source weapon.
Note the weapon type, number of EX-MODs on each source, and the number of EX-MODs on the result. Check whether EX-MODs beyond 4 are dropped or preserved.
Confirm whether the fused weapon keeps the source weapon type. Official sources confirm it does.

Probability or drop mechanics
Whether EX-MODs drop from enemies, are purchased, or are earned through other means is NOT_CONFIRMED.
Optimal combinations
No official source recommends specific EX-MOD combinations. "Best" or "optimal" fusion is a community construct not confirmed by official sources.

Frequently Asked Questions
What is an EX-MOD?
An EX-MOD is a customisation effect attached to a specific weapon. The official demo guide describes them as a core part of the build system alongside Growth Points.
How does weapon fusion work?
Combining two weapons of the same type merges their EX-MODs onto one weapon. The cap is four EX-MODs per weapon. EX-MODs beyond four from the source weapons do not carry over.
What is the best EX-MOD combination?
No official source confirms a best EX-MOD combination. This site does not publish EX-MOD recommendations. Use the fusion checklist and test record above to build your own evidence.
Where is the smithy?
The smithy is located in the Town of Beginnings. This is where weapon customisation and fusion takes place.
Can I fuse weapons of different types?
Cross-type fusion is NOT_CONFIRMED in official sources. The confirmed rule is same-type fusion only.
