Forge Fever Event
Under normal conditions, evolving a unit bumps each of its three Stat Potentials, Damage, Range, and SPA, up by one grade. While Forge Fever is live, that same evolution instead bumps each stat by two grades, so a unit sitting at S grade jumps straight to SSS instead of stopping at SS. Because the boost applies to every evolution performed during the window rather than to a fixed number of uses, it rewards saving up evolution materials and fusing fodder ahead of time so an entire backlog of evolutions can be cashed in at the boosted rate at once.
Like other Boost Events, Forge Fever runs in short, rotating live windows of about four days rather than staying active permanently, and it does not run its own dedicated quest ladder the way Banner Blitz does. Instead, Event Coin is earned passively through normal play and evolution activity during the window, with the event's page pointing players toward the Evolution screen as the place to spend the boosted window.
Event Coin earned during Forge Fever feeds into the same shared Event Shop used across every Event Coin source, so nothing is lost if it is not spent immediately. The shop trades coin for Trait Crystal, Stat Reroll, Stat Lock, Equipment Reroll, Equipment Lock, Sprite (Grey), and Gem, and unspent Event Coin carries forward into whatever Event Coin event runs next.

How Forge Fever works
Forge Fever changes what a single evolution action produces rather than how often a player can evolve. Every evolution performed while the event is live upgrades a unit's Damage, Range, and SPA Stat Potential by two grades instead of the usual one, meaning a fresh S grade stat can reach SSS in a single evolution rather than needing a second evolution cycle to get there. This makes it one of the fastest ways in the game to push a favorite unit's Stat Potential toward its ceiling.
Preparing for the window
Because Forge Fever's boost applies per evolution rather than granting a fixed number of free boosts, the value scales directly with how many evolutions a player can perform during the roughly four day window. Stockpiling evolution materials, duplicate copies, and fusing fodder before the event starts turns the entire backlog into boosted evolutions the moment the window opens, rather than trickling evolutions in at the normal rate across the same period.
Rewards and the Event Shop
Unlike Banner Blitz's dedicated summon quest ladder, Forge Fever does not list its own set of quest milestones; Event Coin instead accrues from playing normally during the event. Whatever is earned spends in the same shared Event Shop as every other Event Coin source: Trait Crystal, Stat Lock, and Equipment Lock at 10 coin each, Stat Reroll and Equipment Reroll in 3-packs for 10 coin, a 5-pack of Sprite (Grey) for 10 coin, and a 200-Gem bundle for 10 coin.
FAQ
How do I trigger Forge Fever in Anime Expeditions?
Forge Fever activates on its own rotating schedule, typically a four-day live window, rather than something toggled by the player. Once it starts, every evolution performed automatically grants the boosted two-grade Stat Potential jump.
What does Forge Fever actually boost?
Evolving a unit normally raises Damage, Range, and SPA Stat Potential by one grade each. During Forge Fever, each of those three stats jumps by two grades instead, for example taking S straight to SSS in a single evolution.
Does Forge Fever have its own quests?
No, unlike Banner Blitz or Headliner Hunt, Forge Fever does not list a dedicated milestone ladder. Event Coin is earned through normal play during the window and spent in the shared Event Shop.
What should I stockpile before Forge Fever starts?
Save up evolution materials, spare copies, and fusing fodder ahead of the window so the entire backlog can be evolved at the boosted two-grade rate as soon as the event goes live, rather than trickling evolutions in afterward.
Is Forge Fever worth using on every unit?
It gives the most value on units whose Stat Potential still has room to climb, since a unit already sitting near SSS across the board benefits less than one starting from a low grade that can leap two full tiers in one evolution.
