Trait Crystals are the only currency that reroll traits in Anime Expeditions, and every reroll burns exactly one crystal. If you want to chase high-end traits like Unbound or Primordial, you need a steady supply of crystals coming in every day, not the handful you pick up by accident. The good news is that the biggest per-run payouts are repeatable, so a short daily loop keeps your stockpile growing.
Quick answer: Open the Challenges menu at the Carrot NPC in the lobby and clear Regular Challenge #1 (School Grounds – Act 1, Hard Mode) for 3 Trait Crystals per run up to 10 times a day, then clear Daily Challenge #1 (Flower Forest – Act 2, Hard Mode) for 10 Trait Crystals. Top up with first-time Story clears, Index claims, the Battlepass, Achievements, and active codes.
Fastest Trait Crystal farm: daily Challenges from Carrot
The Challenges board is the single most efficient crystal source because it hands out fixed rewards you can repeat every day. Walk up to the NPC named Carrot in the lobby and open the Challenges menu. You will see both Daily Challenge and Regular Challenge tabs.
Regular Challenge #1 runs School Grounds – Act 1 on Hard Mode and pays 3 Trait Crystals each clear, with a daily limit of 10 runs. Cleared in full, that alone is 30 crystals per day. Daily Challenge #1 runs Flower Forest – Act 2 on Hard Mode and drops 10 Trait Crystals in a single completion, bundled with equipment rerolls, locks, sprites, and gems.
| Challenge | Stage & mode | Trait Crystals | Limit |
|---|---|---|---|
| Regular Challenge #1 | School Grounds – Act 1 (Hard) | 3 per run | 10 / day |
| Daily Challenge #1 | Flower Forest – Act 2 (Hard) | 10 | Once daily |
Running both fully clears roughly 40 Trait Crystals a day from Challenges before any other source is touched. Because these reset on a daily timer, the loop is short enough to repeat every session.
Other Trait Crystal sources worth clearing
Once the Challenges are done, several other systems pay out crystals. First-time Story completions give the largest one-off bumps, so pushing new stages is valuable while you still have unfinished content. The Index and Achievements convert your normal progress into extra crystals, and the Battlepass drips them across its reward track.
| Source | How it pays out |
|---|---|
| Story Mode | First-time stage completions grant one-off Trait Crystal and gem rewards |
| Index (Unit, Enemy, Equipment) | Claiming index milestones rewards gems and rerolls |
| Battlepass (Season 1) | Trait Crystals spread across the reward tiers |
| Achievements | The Collector, Expeditions, Raid Mode, Secrets, and Story Mode categories award crystals |
| Codes, daily rewards, mail | Free crystals from active codes, daily login rewards, update events, and in-game mail |
| Maps | Clearing maps drops Trait Crystals as you play |
Tip: Check the in-game mail and the code redemption box after every update. Developers frequently push crystals through codes during patches, and those often expire, so redeem them quickly.
How to spend Trait Crystals with Auto Reroll and Filters
You will know it worked when the unit’s Current Trait line updates to the new trait and its passive bonus, and your Trait Crystal count drops by the number of rerolls used.
Trait pity thresholds worth chasing
Because the rarest traits sit at fractions of a percent, the crystal stockpile you build is really fuel for the pity counters. Each top trait has its own guaranteed threshold, so knowing the numbers tells you how many rerolls to bank before you commit.
| Trait | Roll chance | Pity | Passive |
|---|---|---|---|
| Unbound | 0.1% | 1,500 | +350% DMG, -5% SPA, +10% Range |
| Primordial | 0.2% | 750 | +35% DMG, -15% SPA, +20% Range |
| Forsaken | 0.3% | 500 | +35% Crit DMG, +35% Crit Chance, +10% Range |
| Draconic | 0.5% | 300 | +20% DMG, +50% DoT Damage, -10% Unit Cost |
Unbound is the strongest all-around trait thanks to its +350% damage boost, but its 1,500 pity means you need a deep crystal reserve to guarantee it. If you are still building a roster, the mid-tier traits are far cheaper to hit and remain useful across nearly every mode, so save your biggest pushes for the units that matter most. Keep clearing the daily Challenges, and a full pity run becomes a matter of days rather than luck.
