Arcs Neverness to Everness

The 47 Arcs split into three rarity tiers, and the split determines how you should spend both Tri-Keys and time.

• 26 S-rarity — the chase tier, pulled through the gacha with an 80-pull hard pity. But an S-rarity Arc is still class-locked: pulling one outside every class your current roster covers means it sits unused until you get a matching character.
• 16 A-rarity — the realistic mid-investment tier for a character who doesn't hold a matching S yet; several perform close enough to their S counterpart to be worth building instead of waiting on pity.
• 5 B-rarity — the starter tier, obtainable outside the weapon gacha through normal progression. These exist to fill the slot immediately, not to be a long-term answer.

Rarity alone doesn't decide value here — a high-rarity Arc that doesn't match a character's class tag can't be equipped at all, so check the class tag on a card before weighing its rarity.

Every character and every Arc carries one of 5 class tags, shown here as Type I-V. That labeling is intentional — no officially localized name for the 5 classes has surfaced in any language client yet, so this kho shows the neutral roman label instead of guessing. If you spot a fancier nickname for a class somewhere else, treat it as an unofficial community shorthand, not a confirmed in-game term.

• A character can only equip an Arc sharing their own class tag — a mismatched tag simply cannot go into that weapon slot, there's no partial benefit.
• This is a hard compatibility rule, not a soft recommendation, so it's worth checking a character's class tag before spending Tri-Keys chasing a specific S-rarity Arc.
• Filtering this kho by class tag first, then comparing rarity within that narrower list, is a more useful way to browse than sorting by rarity alone.

This index isn't just a list — each card is a starting point for a decision, and it's built to be filtered rather than scrolled top to bottom.

• Filter by rarity and class tag together to see only what your current roster could actually use.
• Every card links out to its own detail page for the breakthrough and star-refinement curve, and back to the matching character's build page — check that build page for the specific Arc actually recommended before spending anything, since a strong-looking S-rarity Arc can still underperform a lower one that fits a kit better.
• Because pity accumulates and carries over across every Arc banner, it's worth checking this kho against the gacha explainer before a new banner opens — you may already be closer to a guaranteed pull than the fresh count suggests.
