Chests

Chests are the open world's main reward for exploring it, and the most of what an area's exploration progress counts. Their places are built, and an opened Common, Exquisite or Precious chest pays its wallet share, as the as-built page records. What is left is what else an opening gives, the locks, digging and seals that hold some of them shut, and the join that makes an opened chest count toward the achievements.

Decisions

• Opened with F, rewarded two ways. Its Primogems, Adventure EXP, Mora and Sigils go straight to the wallet and the bag. Its weapons, artifacts and Character EXP materials pour out as drops to pick up, as the enemies' drops are, or go straight to the bag where the chest stands somewhere a drop would fall away. Of the wallet's part, a Common, Exquisite or Precious chest's Primogems and Mora are built. The drops' pools are the wiki's: each tier's weapons, the artifact sets it can give, and its Character EXP materials by star. An artifact a chest gives is rolled by the artifact enhancement page's rules.
• A locked chest waits on what is beside it. As the wiki describes, a locked chest opens once the enemies near it are defeated or the puzzle near it is solved. Which camp or puzzle locks which chest is listed nowhere per chest, so a chest is locked by the camp or the puzzle whose reach it stands in, the reading closest to the rule the wiki gives, and stands unlocked where it stands in none.
• Hidden chests are dug up. A chest the map marks as buried offers Dig when the player stands at its place, and appears when dug.
• Sealed chests are freed first. A chest sealed in Dendro vines or ice is freed by Pyro, and one sealed in rock by a blunt attack or one that deals poise damage, through combat's hits. The map's sealed label does not say which seal a place holds, so which one each place holds is measured, not read.
• A dug or freed place's tier is unsettled. The map gives a buried or a sealed place no tier, and no tiered chest stands within reach of one to read it off. What a dug or freed place holds is settled by a recording of one, and until then a dug or freed place is left unrewarded, a provisional call.
• Luxurious and Remarkable are unrewarded for now. The wiki gives a Luxurious chest its Primogems and Adventure EXP but leaves its Mora unstated, and a Remarkable chest outside Tsurumi Island gives 5 Primogems and blueprints, Tsurumi's only its blueprints. Both wait until their rewards are settled, and until then they stay unopened.
• The reward ranges are the wiki's, not banded by Adventure Rank. The wiki's chest reward table lists one range per tier, so no Adventure Rank band is read from it. The chest levels by zone (1, 6, 11, 16, 21 and 26) are read from the game's tables, and the Primogems of the high zone-level areas differ from the default. Which areas those are needs the region outlines, so a chest's band waits on them.
• A chest's row is named by its kind. The game's text holds each kind's name under several ids, none of them a chest gadget's own name in the gadget table, so a row is named by the first numeric id genshin:text find prints for the kind's English name: 219297138 for "Common Chest", 104751454 for "Exquisite Chest" and 3752292187 for "Precious Chest", as GameTextKey.CommonChest, ExquisiteChest and PreciousChest. The user's eyes check the words against the game's own prompt.
• A chest stands in as a box until it is measured. The world draws it as a toon box on its ground point, as the drops and residents stand in as spheres and capsules, its size and colour provisional until a recording's chest is matched.
• A chest opens once. Opened chests never come back, kept with the player's progress, and each counts once toward its area's exploration progress and its region's chest achievements.

Scope and order

Built: the chests' places, the seven kinds written per region as the as-built page describes; and the opening of a Common, Exquisite or Precious chest, its Primogems and Mora rolled into the wallet once.

This adds, in order:

packages/genshin-world/src/
├── composables/useWorldChests.ts
└── services/chest/
    ├── computeChestInteractables.test.ts
    └── readMondstadtChestPlaces.ts

1. Mondstadt's chests in the world, opened on F. The Primogems and Mora are built for the Common, Exquisite and Precious kinds, and Windrise's own area waits on the region outlines the exploration progress reads, since the places name no catalogue area. Add readMondstadtChestPlaces.ts, a dynamic import of the existing generated/chests/mondstadt.json parsed with a chestPlaceSchema added beside ChestPlace, as services/gathering/readMondstadtGatheringPlaces.ts reads its slice, and services/chest/computeChestInteractables.ts, which gives each unopened chest of a kind ChestKindRewardMap rewards as an InteractionKind.Open row on the ground under its point, named by its kind's key above. useWorldChests.ts loads the places as useGatheringPoints loads its own and holds the opened ids, and components/World/Session/Index.vue adds its rows to interactables and, on F at one, runs openChest with the world's seeded random, sets the wallet and hands the drops to placeWorldDrops at the chest's point. components/World/Interactables/Index.vue draws the Open rows as box stand-ins (CHEST_STAND_IN_SIZE, CHEST_STAND_IN_COLOR and a CHEST_STAND_IN_CAPACITY above the region slice's count, in services/interaction/constants.ts). The opened ids are a save slice: openedChests in GenshinSave (models/chest/OpenedChestSave.ts, at most MAX_OPENED_CHEST_COUNT in services/save/constants.ts), read and written by readGenshinSave and toGenshinSave, and kept as the account's copy by mergeGenshinSave, with the wallet and the bag, never unioned, as the save data proposal's paid-set rule says. GameTextKey gains the three keys, whose words pnpm -C scripts genshin:text write then writes. Tests: computeChestInteractables.test.ts, asserting that an unopened Common chest is offered and an opened one, a Luxurious one and a Buried one are not; and a case in services/save/mergeGenshinSave.test.ts that the account's opened chests are kept over the guest's.
2. The other rewards and tiers. Adventure EXP and Sigils, which the wallet does not hold yet; Luxurious and Remarkable, once their Mora and blueprints are settled.
3. The locks by camps. Waits on the reach a camp locks a chest within, measured.
4. Digging and seals, once a recording settles what a dug or freed place holds and which seal each sealed place wears.
5. Locks by puzzles, once the puzzles stand.
6. The join to the achievements and the exploration progress. An opened chest moves the 66 chest achievements and its area's doings only once it is joined to the game's own chest records (below), which the scene group export the other machine is making carries with each chest's gadget id and group. The area each chest counts toward is read from the same export, or from the region outlines the exploration progress reads.

Data and measures

• Read from the wiki: each tier's Primogem and Mora ranges (built), and the drop pools: the weapons, artifact sets and Character EXP materials by star, encoded as provisional pools for the weapons and materials. The artifact pieces wait on an artifact drop model.
• Not on the wiki: Luxurious's Mora.
• Read from the game's tables: ChestLevelSetConfigData's chest levels by zone (above). GadgetExcelConfigData names 270 gadgets of the Chest type, the chest templates such as 70210001.
• The join is not made. A placed chest has the map's point id and no game id, while the achievements' TRIGGER_OPEN_WORLD_CHEST lists its chests as ;-joined template ids, with a second list of what appear to be region group ids, and the exploration doings name their chests by their own numbers. Joining a placed chest to its template and group needs the game's scene data, which the AnimeGameData dump carries per scene and is reachable from the build's network. Until that join exists no opened chest moves an achievement or an area's exploration, and a script that makes it is the next data step.
• Measured: the reach a camp or a puzzle locks within, against the chests the map marks beside them, how a chest opens, read off a recording of one, which seal each sealed place holds, what a dug or freed place gives, and the spread of each reward within its range.
