How many Thermal Cores does your build list actually need?
Set what you want to make. The tool totals the Thermal Cores, including the ones hidden inside AI Core, then breaks them down into the six raw materials and the total crafting work. Recipes are cross-checked against three sources; see the Thermal Core guide.
What are you building?
Every figure is one at least two databases give the same number for. The Wing Pack line already accounts for the 20 AI Core it also needs.
Boss runs
Aegidron and Jetragon each drop 1–2 at 100%. No database publishes how that splits, so this shows the guaranteed range rather than an assumed average. Overworld alphas respawn on the in-game day cycle — near an hour at default day length, but that is a world setting and community observation, not documented.
What one Thermal Core is made of
| Step | Makes | From | Work |
|---|---|---|---|
| Corrosive Solvent | 1 | 1 Venom Gland + 1 Sulfur | 0.03× |
| Hexolite | 1 | 1 Chromite + 1 Hexolite Quartz | 1× |
| Thermal Core | 1 | 4 Flame Organ + 8 Coal + 2 Corrosive Solvent + 2 Hexolite | 1× |
Work is shown relative to the Thermal Core step, so one finished core is about 3.1× that step once both sub-crafts are counted. No absolute figure is given: three databases give 500,000 and a fourth 5,000, a clean factor of 100, while all four agree exactly on the proportions. Verified 4 August 2026.
