A Fire-type DPS at Nova Stage, Infergon cannot be found in the wild. To recruit one, evolve a Jawling through its line; that route requires defeating a world boss, meeting a strict quality standard, and having a particular crafting material. Unless all three requirements are met, Infergon will not appear as an evolution choice.
Quick answer: Beat the Omega Infergon boss in Russet Highlands, level a Perfect-rated Jawling or Helmwhelp to 48, then spend 1 Blaze Stone and choose the Infergon branch instead of Helgon.
Infergon evolution requirements
Infergon is a special Nova evolution from Helmwhelp, branching away from the usual Helgon route. The game allows the evolution only when all four requirements are met simultaneously.
- You must defeat Omega Infergon at least once.
- A base Aniimo starts with a potential rating of Perfect.
- The Aniimo has reached level 48.
- You own at least 1 Blaze Stone.
Fire-type Aniimo evolve using Blaze Stone, which you can get by defeating Alpha Aniimo. Make sure you have at least one before beginning.
Mountain Jawling and Mountain Helmwhelp cannot become Infergon. Those golden-tinted variants only lead to Mountain Helgon, so work with a standard chrome-skinned Jawling or Helmwhelp.
The evolution chain: Jawling to Helmwhelp to Infergon
The line has two evolutions before reaching Infergon: Jawling becomes Helmwhelp at level 38, then Helmwhelp can evolve into Infergon after all four requirements are met. In Helmwhelp’s evolution screen, select Infergon instead of Helgon.
If Infergon is not your goal, Helgon is the other branch. To unlock it, open 30 chests across the world in total and raise the Aniimo to level 48.
Defeat Omega Infergon in Russet Highlands
The first unlock step is defeating the Omega Infergon world boss. The boss is in central Russet Highlands, on a volcanic slope where Helmwhelps patrol, and its world map marker reads Lv.55 Infergon. Aim for a team around level 55.
To reach it, speak with Sorora, the Mysterious Painter near the western edge of the region to begin the Warrior side quest. That quest ties into the main story quest Ancient and Sacred Fragrance, so taking the Flameheart Stone from the arena drops you straight into the fight.
Build your team around Water, Earth, or Dark Aniimo. Infergon is a Fire type focused on Break; Water and Dark deal extra damage to it, while it deals less damage to Water Aniimo. Break-focused teammates can keep Infergon stunned and prevent it from using its most dangerous moves.
Once its health falls below half, it becomes much more aggressive and may use an Ultimate that fills the arena with fire crystals. Break enough crystals to create a safe area, or position yourself outside the overlapping eruption zones, to make it through the final phase. Its health pool is huge; solo fights may take 10 to 20 minutes or more, while co-op can cut the time substantially.
Beating the boss does not let you capture it. The win only flips the evolution requirement to complete, marked by a checkmark on the world map node.
Farm a Perfect Jawling or Helmwhelp
Infergon requires an Aniimo with a Perfect rating, and its potential is set when caught. Since you cannot improve that rating afterward, catch Jawlings in large numbers and check each group for a Perfect one. Be ready for a long hunt: about 200 to 300 catches may go by before one appears.
Cultivate the area with the Branch of Breezy Plains to raise the spawn rate of certain species. Which one gets boosted is random, so it may take several attempts to get Jawling, but this can raise your chance of a Perfect result. A Sparkling Cube ensures a Perfect capture with Sparkling status, but these cubes are scarce; do not spend one on a Mountain form.
Evolve into Infergon
How to confirm it worked
The evolution is done when the transformation animation plays and the Aniimo shows up as Infergon at Nova Stage in your roster. Its AniLog entry (No. 67) fills in, and it gains the Fly pathfinding ability at level 3 for fast aerial travel.
Infergon abilities and role
Infergon’s Fire DPS comes from building up and consuming Fire Debuff stacks. It has an edge over Ice and Grass, but Water and Earth are its weaknesses. Its Power of Fire trait adds 10% damage against targets with over five Fire Debuff stacks, so managing those stacks is key to its rotation.
| Skill | Type | EP Cost | Power |
|---|---|---|---|
| Lava Breath |  Fire | 20 | 62 |
| Flaming Claws | Combo | 15 | 45 |
| Fiery Charge | Dash | 20 | 60 |
| Lava Breath | Fire | 0 | 35 |
| Hot Breath (Ultimate) | Fire | Ultimate | 168 |
Flaming Claws is its primary source of damage. You can cast it again within five seconds; every hit uses up two Fire Debuff stacks to deal extra damage. For best results, keep the target above four stacks.
Fiery Charge surges into the target, then dives down when activated in mid-flight. A successful hit gives it a shield worth five percent of its max HP for ten seconds.
Hot Breath, its Ultimate, is a flame attack from the air that covers a broad area ahead and reapplies eight Fire Debuff stacks. Use it whenever available, preferably while the enemy is broken, to maximize the hit and restore stacks for Flaming Claws.
Infergon can also work around your Homeland: Afire level 3 enables cooking, smelting, and providing heat, while Hauling level 3 lets it move stored produce into storage. It still has a role outside your active party.
