How the Arcanis achievements tie to the TCG system

All four named Arcanis achievements are tied to the same in-game TCG system described on the [Arcanis TCG guide](/arcanis/). `Card Collector Arc` (22.5% global unlock) is the entry milestone — finishing the starter collection. `Road to the Finals` (0.1%) is the ladder milestone — reaching a high Battle Rank. `The Legend of Cardmaster` (0.1%) is the mastery milestone — running a fully-built deck to tournament wins. `I am the Champion` (0.1%) is the single-event win milestone. Because all four sit below 25% global unlock and three are at 0.1%, they are the highest-value long-tail goals for a 100% completion run, and they require the 9-card deck and the 5-tournament Secret Shop unlock explained on the Arcanis guide.

Hidden achievements and what they tell you

Steam hides the unlock criteria for any achievement marked hidden, which means the six named here (`Superchew Single`, `Violin`, `EQ`, `Reverb`, `Aiya`, `Woem`) only become visible on your own profile after the unlock fires. Until they trigger, the only confirmed fact is that they exist on the Steam Achievements page and sit alongside the rest of the 38-entry roster. Treat any third-party video or forum post that claims to have decoded their unlock criteria as unverified — Steam does not publish hidden-achievement criteria anywhere.

100% completion path — grouped by gameplay system

Group the 38 achievements by the gameplay system that gates each one. The Steam Achievements page is the only canonical source for which achievement belongs to which group; the cluster list below mirrors the page's grouping: - Story progression: tutorial / first-day / story-milestone achievements. - Shopkeeper rank ladder (E → C → A → S): rank-tier achievements. - Defense: thieves / vandals / litterers counter achievements (see the [shop defense guide](/shop-defense-and-checkout/)). - Card collection: the four named Arcanis achievements above. - Pin collection: collection achievements below 1% global unlock per the launch-week signal. - Keychain collection: collection achievements below 1% global unlock per the launch-week signal. - Manga series: per-series milestone achievements. - Booster gacha: booster-pull and secret-shop achievements (cross-link to Arcanis guide). - Store-form customization: shop-decoration / form / layout achievements. - Hidden items: the six named hidden achievements above plus other hidden entries. A 100% completion run is gated by the rarest entries in each group. Because card / pin / keychain achievements all sit below 1% global unlock, expect the long tail to be the Arcanis mastery chain (`Road to the Finals` → `The Legend of Cardmaster` → `I am the Champion`) and the collection tracks.

100% completion checklist

  1. Step 1

    Open the [Steam Achievements page](https://steamcommunity.com/stats/3393280/achievements) and sort by global unlock percentage to identify the rarest entries.

  2. Step 2

    Clear the story / first-day cluster first so the Shopkeeper rank ladder (E → C → A → S) becomes visible.

  3. Step 3

    Pull enough Arcanis boosters ($5.33 each per the [Arcanis guide](/arcanis/)) to build a 9-card deck that respects the +2 type-advantage rule.

  4. Step 4

    Run the Battle Rank ladder (Common → Bronze → Silver → Gold → Platinum → Diamond) until `Road to the Finals` unlocks at 0.1%.

  5. Step 5

    Win five tournaments to unlock the Secret Shop and trigger the upgraded booster visuals Hotfix 1.0.2 added.

  6. Step 6

    Hunt the hidden achievements (`Superchew Single`, `Violin`, `EQ`, `Reverb`, `Aiya`, `Woem`) and the pin / keychain collection tracks until the 38-entry roster is full.
