Calculator

Example Data Table

Parent A Parent B Race Pair Base Level Math Estimated Result
Sparna, Beast, Level 54 Feng Huang, Holy, Level 36 Beast + Holy floor((54 + 36) / 2) + 1 = 46 Avatar race route near Level 46
Pixie, Fairy, Level 7 Cop Tengu, Yoma, Level 20 Fairy + Yoma floor((7 + 20) / 2) + 1 = 14 Genma race route near Level 14
Naga, Snake, Level 18 Long, Dragon, Level 34 Snake + Dragon floor((18 + 34) / 2) + 1 = 27 Drake race route near Level 27

Formula Used

Needed planning level: floor((Parent A base level + Parent B base level) / 2) + 1.

Result demon: find the output race, then choose the first listed demon whose base level is equal to or above the needed planning level.

Estimated budget: ((Parent A level + Parent B level + optional sacrifice level) × Macca per level) − discount.

Inheritance score: skill pool size, desired skill matches, slots, and moon phase are converted into a planning chance.

How To Use This Calculator

Enter both parent demon names, races, and base levels. Add each parent skill list. Put one skill per line or separate skills with commas.

Choose automatic race mode for quick planning. Use manual result race mode for special fusions, Fiend routes, Deathstone checks, or rank changes.

Edit the race chart and demon table when your compendium route needs exact data. Press calculate. The result appears above the form.

Use CSV for spreadsheets. Use PDF for printable route notes.

Fusion Planning For Nocturne

SMT Nocturne fusion looks simple at first. Two parent demons enter the Cathedral. A new demon appears as the result. The hidden planning work is harder. Race, base level, moon phase, sacrifice choices, and skills all matter. This calculator gives one planning screen for those choices. It is made for fast route testing before you spend Macca or overwrite a useful demon.

Why Base Level Matters

The calculator uses parent base levels, not trained levels. This mirrors normal fusion planning. It averages both parent levels. Then it adds one planning level. The result race is read from the selected race chart or your manual override. The tool then picks the first listed demon in that result race that meets the needed level. You can edit the custom demon table when your route needs exact compendium data.

Skill And Moon Checks

Skill inheritance can decide if a fusion is worth doing. Enter inherited skills from both parents. Add desired skills in a separate field. The calculator compares both lists. It also estimates a planning chance from slot count, skill pool size, and moon phase. Treat this as a route score, not an official random seed. New moon warns you about weak inheritance planning. Full moon highlights volatile inheritance notes.

Cost And Sacrifice Control

Advanced planning also needs cost control. The form includes a Macca per level value and a compendium discount field. It estimates a recall budget from both parents and the optional sacrifice demon. Sacrifice data also gives an experience planning note. This helps compare a cheap route against a stronger route with better inherited skills.

Best Use Cases

Use this page when building a target party, testing race pairs, or comparing skill routes. Start with the example rows. Then enter your own parent demons. Choose auto race mode for quick checks. Use custom race mode when a special fusion, Fiend route, Element rank change, or Deathstone route changes the result. Export the result as CSV for a spreadsheet. Save PDF notes for later play. Always confirm rare special fusions in game. Keep each saved route named clearly. It makes later comparisons easier when several parents can reach the same race and level window during play.

FAQs

Is this an exact official fusion database?

No. It is an advanced planning calculator. You can edit the demon table and race chart to match your own compendium data.

Why does the calculator use base levels?

Fusion planning normally depends on demon base levels. Trained levels can mislead routes, so this form asks for the starting level.

Can I force a Fiend result?

Yes. Choose manual result race, select Fiend, and enable the Deathstone note. Then add Fiend entries to the demon table.

How are skill matches checked?

The calculator compares desired skills against both parent skill lists. Matching names are shown in the result table.

Why is the inheritance chance only an estimate?

Skill inheritance can involve randomness and special rules. This tool gives a planning score, not a guaranteed in-game result.

Can I add more demons?

Yes. Add rows to the custom demon table. Use this format: Race, Level, Name. Keep one demon per line.

Can I change race chart rules?

Yes. Edit the custom race chart. Use this format: Race A + Race B = Result Race.

What is the best export option?

Use CSV when comparing many routes in a spreadsheet. Use PDF when saving a readable fusion note.
