Stardew Valley - Geodes

Geodes are the stones the blacksmith cracks open. Each kind holds its own list of minerals, ores and the occasional artifact.

Overview

A geode is a sealed stone, and the whole branch turns on the fact that nobody can see inside one. Four shells exist, each with its own list of contents, and every one of them has to be broken before it means anything. Clint cracks them at the anvil for a small fee, and a Geode Crusher placed on the farm does the same job for a lump of coal. Until one of those two happens, a geode is a lottery ticket taking up a slot in the bag.

The shells are the main reason a mining run matters beyond its ore. Inside them sit the stones that exist nowhere else in the valley, a handful of dwarvish relics the Museum wants, and the ore and coal that pay for the next tool upgrade. A farm that ships its geodes unopened has sold the Museum collection it was carrying without ever seeing it.

Luck has nothing to do with it. Daily fortune and food buffs change a great many things in the valley, but not the contents of a geode, so a stack can be opened on any morning. What does change the odds is the Mining skill. Excavator doubles how often geodes appear in the rock, and Geologist gives any node a chance of handing over two stones instead of one.

Groups

Three of the four shells are tied to a depth band and read as a progress report. The plain grey shell belongs to the top of The Mines and to the rocks on the farm itself. The frozen one belongs to the icy middle floors and turns up in farm soil during Winter. The magma one belongs to the lava floors and to the crates of the Skull Cavern.

The fourth, the Omni Geode, is the odd one and by far the most important. It starts appearing from the twenties downwards, it can hold anything that any other shell can hold, and it is the only shell that doubles as a currency. The Desert Trader deals in them, which gives a farm with a full chest of them access to artifact troves, warp totems, hay and a pair of absurd hats.

A fourth group, strictly speaking, is the pair of nodes rather than the loose stones. Quarry farms carry fixed geode nodes that regrow, and the volcano carries omni nodes, which makes those maps the only places where geodes can be mined to a schedule rather than hoped for.

Order

A new farm meets the plain shell in its first week, from the rocks on the land and from the first floors of the shaft. Those early geodes are the reason the first trips to the blacksmith happen at all, and the ore inside them often funds the copper tools before the mine does.

The frozen shell arrives with the lift at floor forty and with the first Winter, when tilling the farm's soil starts turning them up. The magma shell waits for the lava floors, by which point a furnace is standing and the Gold Ore inside it is worth more than the stone itself.

The omni shell is met early and understood late. It appears from the twenties onwards, but its value only becomes clear once the bus runs and the Desert Trader is reachable, and clearer still once the Skull Cavern is open and omni geodes arrive by the dozen. A farm that kept them from the start is a farm that can buy artifact troves by the handful in its second year.

Locations

Rocks are the first route and the dullest. Beyond them, fishing treasure chests carry all four shells, which makes a rainy day with a rod a mining trip by other means. Monsters supply the rest: Duggies drop the plain shell a quarter of the time, and the Carbon Ghosts that haunt the mummy floors of the Skull Cavern drop an Omni Geode almost every single time they fall, which makes them the most profitable monster in the game to hunt deliberately.

Fish ponds produce them once a population grows large enough, each pond matched to a shell: Stonefish to the plain one, Ice Pip to the frozen one, Lava Eel to the magma one, Octopus to the omni one. Shops sell them too. The Oasis offers a few omni geodes on Wednesdays, Krobus offers one on Tuesdays, and Sebastian trades frozen geodes for Calico Eggs during the Desert Festival.

The odd corners are worth remembering. A meteorite that lands on the farm gives up omni geodes when it is mined out. The Garbage Can outside the Museum turns up shells of every kind. Supply crates washed onto the Beach Farm hold plain geodes before the farmhouse is upgraded and omni geodes afterwards. Artifact spots on Ginger Island hold omni geodes, and villagers hand geodes over as presents at the Feast of the Winter Star.

Uses

What a geode is for depends on whether the Museum is finished. Before that point every shell goes to Gunther by way of the anvil, because the stones inside are the only way to fill a long row of the cases, and the Dwarvish Helm and the Ancient Drum come out of the same shells.

Once the collection is full, the branch becomes a supply line. The ore, coal, clay and stone inside pay for building and smelting, the spare minerals go into the Sewing Machine or the dye pots, and the omni geodes become the Desert Trader's money. Five of them buy an Artifact Trove, three buy a Warp Totem to the desert, one buys a morning's hay on Mondays, fifty buy a turban, and the two magic hats cost a quantity that only a very long run reaches.

The frozen shell has one job of its own: the Field Research Bundle on the Bulletin Board asks for it unopened, so one should be set aside rather than cracked. The raccoon living in the Giant Stump asks for geodes by the handful as well, and the three sealed shells each tailor into a different coloured hoodie.

Prices

Three of the shells are worth more opened than sealed, and the arithmetic is not close. A Magma Geode is the dearest sealed shell in the branch, and the minerals inside it routinely fetch several times that, with Star Shards alone worth three times the stone that held it. The one shell the shipping bin will not take at all is the Omni Geode, which is the game's blunt way of saying it was never meant to be sold.

The fee at the anvil is small enough to ignore on a handful and real enough to notice on a stack of a hundred. The crusher removes it entirely at the cost of one coal per stone and one in-game hour, which means a farm with coal to spare opens geodes for free overnight while a farm short of coal is better off paying Clint. Clint is also the only one who will open an Artifact Trove, a Golden Coconut or a Mystery Box, so the two routes coexist rather than compete.

Strategy

Build the crusher as early as the recipe allows. It arrives from Clint himself after a monster-hunting commission on the town's special orders board, and it costs two gold bars, fifty stone and a diamond. A pair of them running through a chest of geodes while the farmer is in the fields is worth more than any single day at the anvil.

Keep every Omni Geode until the Desert Trader has been visited. Nothing else in the branch has a second life as currency, and the trove trade in particular is how a stalled Museum collection gets finished.

Hunt the ghosts rather than the rocks once the desert is open. A week spent killing Carbon Ghosts on the mummy floors of the Skull Cavern fills a chest with omni geodes faster than any amount of careful mining, and the same week clears the Guild's monster goals.

Notes

Two of the contents lists quietly change as a farm digs deeper. A plain geode gives Copper Ore in place of iron until floor twenty-six has been reached, and a Frozen Geode gives iron in place of gold until floor seventy-six. Opening a hoard early therefore produces a poorer haul than opening the same hoard later, which is an argument for letting them pile up.

The Prismatic Shard inside an Omni Geode has a floor under it as well. The first fifteen omni geodes a farm opens cannot produce one at all, so the famous chance only begins once the habit is established.

Rocks broken on the very first morning of a save hold no geodes, which is why a first day spent clearing the farm feels unusually thin. From the second day onwards the ordinary odds apply, and clearing the land becomes the cheapest geode source a first-year farm has.
