Anvil Stat System
Stat Anvils only exist inside Expedition Mode, where the tutorial introduces them at the very first checkpoint alongside Payload repairs and unit hires. Buying an anvil rolls one of 15 possible stat types, covering everything from raw Damage and Range multipliers to Expedition-specific bonuses like Payload Health, Summon Health, Yen Generation, and bonus match rewards, and each roll is weighted toward the more common rarities: Epic accounts for 60% of rolls, Legendary 30%, and Mythic just 10%, with a small independent chance for a bonus Rainbow-tier roll on top.
Rarity directly controls the strength of the stat gained. An Epic-tier Damage anvil lands in a modest 1 to 4 percent range, Legendary jumps to 5 to 7 percent, Mythic reaches 8 to 10 percent, and the rare Rainbow tier pushes as high as 11 to 13 percent, with the exact bands varying slightly per stat type, since SPA, Range, and EXP Multiplier each use their own scaling table. Several stats are capped outright regardless of how many anvils are stacked, such as SPA capping its total reduction at 50% and Summon Health capping at 200%, preventing infinite stacking from breaking the mode's balance.
Because anvils are bought and applied within a single Expedition Mode run rather than being permanent account progression, the system functions as a per-run build tool: a player deciding between an offense-heavy Expedition (stacking Damage, Crit Damage, and Element Damage anvils) versus a defense-heavy one (stacking Payload Health and Summon Health anvils) is making a real strategic choice that resets the next time they start a new run.

How rolls and rarity work
Every anvil purchase rolls both a stat type from the pool of 15 and a rarity tier independently, with rarity weighted toward the common Epic tier and scarce at Mythic and Rainbow. Stats like SPA and Range use Multiply-type scaling while others like Damage and Summon Health use Add-type scaling internally, which is why some stats have hard caps (SPA at 50%, Payload Health bonus capped at 50%, Summon Health capped at 200%) to stop a single Expedition Mode run from stacking a stat into an unbalanced extreme.
Building an Expedition loadout
Because anvils apply per Expedition Mode run rather than permanently, players effectively choose a build identity each time they queue in. Damage, Crit Damage, and Element Damage anvils push a glass-cannon offensive loadout, while Payload Health and Summon Health anvils prioritize surviving longer routes with tougher checkpoints. Bonus Match Rewards and EXP Multiplier anvils are more of a meta-progression pick, boosting the value of the run itself rather than combat performance directly.
Anvils vs. Ascension and Stat Potential
Stat Anvils are easy to confuse with the game's other two stat-modifying systems, but each works on a different timescale. Ascension permanently raises a Mythic unit's Damage and Range by consuming duplicate copies, and Stat Potential rerolls a unit's underlying Damage, Range, and SPA grade using a Stat Reroll, and both carry forward between sessions. Stat Anvils do neither: they are bought fresh with in-run currency at an Expedition Checkpoint and vanish the moment the run ends, so a fully ascended, well-rolled unit still starts every new Expedition Mode run with a blank anvil slate.
Reading the rarity odds
With Epic landing 60% of the time, most checkpoint purchases produce a modest 1% to 4% bump on whichever stat rolled. Legendary at a 30% weight and Mythic at 10% are where anvils start meaningfully swinging a run, and the Rainbow tier sits outside that base distribution entirely as a rare bonus roll capable of pushing a single stat as high as 11% to 13%. Because rarity and stat type roll independently, a player cannot target a specific stat and rarity combination directly, only buy repeatedly and bank the strongest results that land.
FAQ
Where do I get Stat Anvils in Anime Expeditions?
Stat Anvils are purchased at Expedition Checkpoints, the safe zones reached while progressing through a run of Expedition Mode.
How many stat types can Stat Anvils roll?
15 distinct stat types, ranging from combat stats like Damage, Range, and Crit Chance to Expedition-specific stats like Payload Health and Yen Generation.
What is the rarest Stat Anvil tier?
Mythic is the rarest of the three standard tiers at a 10% roll weight, though a separate, even rarer Rainbow tier can also appear, granting the strongest possible stat range.
Do Stat Anvil bonuses carry over between Expedition runs?
No. Anvil bonuses apply within the Expedition Mode run they were purchased in, making the anvil system a per-run build choice rather than permanent account progression.
What is the difference between Stat Anvils and Ascension?
Ascension permanently upgrades a Mythic unit's Damage and Range by consuming duplicate copies, while Stat Anvils only apply for the current Expedition Mode run and reset every time a new run starts.
Which stats have a hard cap on Stat Anvils?
SPA is capped at 50% total reduction and Summon Health is capped at 200%, along with other stats that carry their own internal ceilings, preventing a single run from stacking one stat indefinitely.
Should I buy offense or defense anvils?
It depends on the run. Damage, Crit Damage, and Element Damage anvils suit a glass-cannon offensive build, while Payload Health and Summon Health anvils help a team survive longer or harder Expedition Mode routes.
