Editing Delving

'''Delving''' is the [[Skills|skill]] of descending into [[Caves|caves]] beneath the world. Each biome has one cave that opens once the biome is fully cleared, and delving into it grants Delving XP alongside cave materials, gems, blueprint sheets, and rare best-in-slot unique gear. Delving also governs the [[Excavation]] panel, where you spend Dig Site Maps to run fossil digs.

Delving levels run from 1 to 99. Higher levels unlock deeper caves and more [[Excavation]] dig slots.

== How delving works ==

A cave run resolves much like an [[Expeditions|expedition]]: it uses the same combat math (your gear plus your companion party against the cave's difficulty), fleeing works, and injuries can occur. But there are two important differences:

* '''A light fuels every run.''' Each cave burns its own crafted light, spent whether you '''win or lose''' — the [[Torch]] that opens the Sunlit Grotto is only the first rung; every deeper cave wants a tougher light crafted further up the same [[Crafting]] bench (Pitchwood Brand, Bogfire Lamp, and so on, up to the Deeplight Lantern for the Amber Door — see '''[[#Cave lights|Cave lights]]''' below). Unlike an expedition, the entry cost is paid the moment you step in.
* '''Cave injuries hurt double.''' An injury from a cave takes about '''60 minutes''' to heal, twice as long as a surface [[Expeditions|expedition]] injury (about 30 minutes). Cave difficulty sits between a biome's patrol and its Guardian.

Cave wins do '''not''' advance biome-clear progress and cannot defeat Guardians — clearing is done through [[Expeditions]]. Caves are purely a reward activity.

== Caves and level gates ==

Each cave requires the biome to be 100% cleared and a staggered Delving level.

Percentages in the Outputs column show the chance of a bonus drop per winning run; unmarked items are produced every time. Interval is the base time before speed bonuses; Inputs is the light each cave burns (see '''[[#Cave lights|Cave lights]]''' below). Every winning delve also rolls the shared reward layers covered under Rewards below — Expedition Set pieces, Arena Artifacts, and Dig Site Maps — which work the same for every cave and so aren't repeated per row.

The '''[[Caves#The Amber Door|Amber Door]]''' is an eleventh cave — a deeper Sundered Vale site that opens only once you hold '''The Sigil''' (the [[Chronicles]] reward), on top of the level and light requirements above.

== Rewards ==

Every winning delve rolls several loot layers:

* '''Cave materials''' (common) — Stalactite Chip, Glow Moss, Cave Pearl, Echo Shard. Common crate filler with decent sell value.
* '''Gems''' (uncommon) — Rough Garnet, Deep Sapphire, Ember Topaz, and Sky Opal, tiering up by depth; pure [[Items|Amber]] income.
* '''Unique gear''' (rare, about 0.2% per win) — an uncraftable piece from '''every''' cave (eleven in all, one per cave). A dry streak is capped too: 400 winning runs at a cave without its unique guarantees the drop on the 400th. See [[Caves]] for the full list.
* '''Blueprint sheets''' — Glacier Hollow, Ashen Gallery, and Vale Abyss each drop a forge [[Blueprints|blueprint]] sheet at 4% per win (Frostbound Barding, Wardstone Bulwark, and Wardweave Leggings respectively); the Amber Door offers a second, 6% chance at that same Wardweave Leggings sheet.
* '''Expedition Set pieces''' — the biome's [[Expeditions|set]] pieces drop from caves at roughly 0.8% per piece per win, faster than on patrols.
* '''Arena Artifacts''' — a biome's cave is the '''only''' source of its Arena Artifact (about 1.5% per win), the key required to challenge the [[Arenas]]. A dry streak is capped: if the artifact hasn't dropped in 20 winning runs, the 20th guarantees it.
* '''Dig Site Maps''' — caves are the best source of a biome's [[Excavation]] map (about 3% per win).

== Cave lights ==

Every cave needs its own light before you can delve — burned on entry, win or lose, and a delve cannot start without one. Lights are crafted on a [[Crafting]] ladder that runs alongside the caves themselves: the Sunlit Grotto's plain [[Torch]] comes from fernwood, fiber, and resin at Crafting level 5, and each rung after it leans more on the cave materials the deeper caves themselves drop (stalactite chips, glow moss, cave pearls, echo shards), so a good run helps restock your own next light. A fresh save needs a little Crafting (to level 5) before its very first delve; from there, each light's Crafting level sits below its own cave's Delving level, so the ladder never locks you out of the next rung. Every recipe yields several lights per craft (six, except the Deeplight Lantern's three). See the '''Inputs''' column above for exactly which light each cave burns.

== Excavation ==

The [[Excavation]] panel lives on the Delving page. Spending a Dig Site Map starts a real-time dig that delivers fossils, Delving XP, and rarely a creature skull. The number of dig slots you can run at once grows with your Delving level. See [[Excavation]] for details.
