Crafting & Material Fusion
Every upgrade material in NTE is built the same way: fuse 3 of one tier into 1 of the next for 100 Beetle Coins. This is the full map of all 14 fusion chains — character ascension, skill upgrades and Arc ascension — so you know exactly what feeds what.
In this guideHow material fusion works and the full map of every chain. It doesn't list where each base material drops — that's the farming side.

How fusion works
There's no recipe variety to memorise — the whole system is one rule applied to every material. You combine three copies of a tier plus 100 Beetle Coins to get one copy of the next tier up. Base materials drop in the open world; the higher tiers only exist by fusing.
Tier 2 needs 3× Tier 1. Tier 3 needs 3× Tier 2. Each fusion costs a flat 100 Beetle Coins, the same across all 28 recipes.
Every fusion chain
The 14chains across the three crafting systems. Read each row left to right — that's the path from a base drop to its capstone material.
Character Ascension
4 chainsMaterials that raise an esper's ascension. Four chains, one per drop family.
Skill Upgrade
5 chainsMaterials for levelling skills. Five chains feeding the skill tree.
Arc Ascension
5 chainsMaterials that break-limit your Arcs. Five chains for weapon upgrades.
What one tier-3 material really costs
Because the ratio compounds, a single capstone material is more expensive than it looks. The maths falls straight out of the 3:1 rule:
Beetle Coins4 crafts × 100So the real bottleneck is the base-material grind, not the coins — 9 drops per finished tier-3. Plan your farming around the few materials your active espers and Arcs actually consume rather than fusing everything you collect.
What the data doesn't give
- The recipe data doesn't say where each base material drops — for hunting routes, use the Anomaly Farming guide.
- It doesn't map a material to the exact esper or Arc that needs it; check the character's own build guide for its pre-farm list.
- Which chain to prioritise is account-specific — fuse for who you're building now, not for a full collection.
Chain names, the 3:1 ratio, grades and the 100-coin cost are all read directly from the recipe data. The cost breakdown is plain arithmetic on that ratio — nothing invented.
