Stardew Valley - Monsters

Monsters live underground, in the caves, the Skull Cavern and the volcano, and on the wilderness farm at night. Each one moves and attacks in its own way, and each drops materials the farm and the forge need. Deeper floors hold stronger versions of the same creatures.

Overview

Everything that fights back in this valley lives underground, with one deliberate exception. A roster of its own waits in the mountain shaft, in the little pit under the quarry, in the caverns beyond the sand, in a flooded lair off the sewers, inside the island's burning volcano and in the clearing behind the fallen log, and a farm can invite the same creatures onto its own land if it chooses to. Every one of them costs health on contact, pays combat experience when it falls, and leaves something behind that a bundle, a kitchen or a crafting bench wants.

The branch is built around a single idea that catches almost every farmer out at least once: not everything down there looks like a monster. A rock on a mine floor, an iridium node in the caverns, a piece of driftwood, a mushroom on a volcano ledge and even a truffle in the grass can each turn out to be an animal with a shell on its back. The tell is always the same. Hovering the cursor over a genuine forageable shows a small green cross, and a creature in disguise shows nothing, which makes the cursor the most useful weapon in the branch.

The second idea is escalation. Switching on the Shrine of Challenge inside the mine, or the statue at the mouth of the caverns, replaces the whole roster with tougher versions of itself, each with its own sprite and with more health, more damage and often more armour. Speed stays the same and so does the experience paid out, so the dangerous roster is a choice about risk and loot rather than a faster way to level. Three creatures exist only in that mode, and each of them lands a debuff rather than simply a blow.

Groups

Behaviour sorts this branch far better than geography does. The chargers simply run at whatever is nearest and hit it: bugs, dust sprites, crabs once they are out of their shells, slimes of every colour and the serpents that swarm the deep caverns. They are dangerous in numbers rather than one at a time, and a wall at the farmer's back answers most of them.

The flyers ignore the floor plan. Bats, haunted skulls, ghosts and the carbon version of them cross rock, empty space and the black gaps at the edge of a level, and several teleport away after landing a hit instead of staying to fight. Against these a slow heavy swing beats a quick light one, because a hit knocks them back several tiles and a weak hit simply resets the wait.

The ranged ones are the newest problem. A Squid Kid throws fireballs from a distance, a Pepper Rex breathes a wall of flame while standing still, a sentry in the volcano barely moves but refuses to be pushed, and the specialists on the dangerous roster fire orbs that weaken, slow or darken. Cover and footwork matter more than damage here.

The last group needs a trick rather than a weapon. A mummy collapses into a pile of bandages and stands up again at full health after a few seconds unless a bomb finishes it while it is down, and a blade with the right enchantment or the holy sword does the same job without explosives. An armoured bug in the caverns shrugs off every ordinary weapon and only falls to a blade enchanted against insects, so the sensible response to one is to clear the stones out of its flight path and walk around it. The crabs and their disguised cousins are untouchable while hiding and have to be knocked loose with a pickaxe first.

Order

The mine introduces its roster in bands, and the bands are a reliable map of how far down a farm has got. The first thirty floors hold grubs, cave flies, bugs, the burrowing duggies and the first disguised crabs. The thirties add bats and stone golems. The icy stretch from the forties to the seventies brings dust sprites in packs, frost bats, ghosts and skeletons. The lava floors below the eighties hold metal heads, lava crabs, squid kids and the two shadow creatures that the guild lists as void spirits.

The Quarry pit is a short detour with three residents of its own, two of them metal slimes and the third a flying skull that screeches before it arrives from off the edge of the floor. Past that, the caverns under the desert drop the orderly bands entirely: mummies in tomb rooms, prehistoric lizards on bone floors, serpents everywhere, iridium crabs from the mid twenties downwards and carbon ghosts wherever the mummies are.

The last two places belong to a mature farm. The bug lair behind Krobus holds endless mutant flies and grubs in a confined space, which makes it the branch's best training ground. The volcano adds creatures made of fire, including the mushroom that is not a mushroom and a slime that only exists on the island.

Best

A few creatures are worth hunting on purpose rather than killing because they got in the way. Carbon ghosts are the pick of the branch: they haunt the mummy floors of the caverns, they die to a patient swing, and they hand over sealed shells at a rate no amount of careful mining matches. A week spent on those floors fills a chest and clears a guild goal at the same time.

Dust sprites are the best early target. They travel in packs on the icy floors, they are the richest supply of coal in the game, and the walk back to the mine entrance resets every floor, so the same pack can be farmed again and again in an afternoon. Their guild goal is also the one that pays out the ring that doubles every monster's loot, which makes them an investment rather than a chore.

Two creatures pay in items nothing else drops. A prehistoric lizard gives up exactly one bone or one Dinosaur Egg each time it falls, and that egg is the only way a farm gets a dinosaur without the trader's luck. An Iridium Crab gives ore by the handful along with the occasional gem, which makes the caverns worth searching for fake nodes rather than only real ones.

Uses

Monster loot is the quiet engine behind a lot of crafting. The slime, essence, Bug Meat and bone that drop down here feed bombs, totems, lightning rods, fertiliser and a long list of rings, and the kitchen turns Bug Meat into a dish that is better than it sounds. The Community Center asks for a small handful of these drops as well, which is why a first-year farm with no interest in fighting still ends up carrying a sword.

The scoreboard for all of it hangs in the guild hut by the mine entrance. Gil keeps a list on the wall of how many of each kind have fallen, and each total he is satisfied with pays out an item: a ring that makes slimes harmless, a ring that heals on a kill, a ring that speeds the farmer up after one, a ring that rolls the loot table twice, and three pieces of headgear. Marlon sells those rewards back afterwards, so a lost one is recoverable, and the back room of the hut opens once the overall tally is high enough.

Beyond the guild, kills feed the quest journal and the order boards. A monster commission from the town board, a monster hunt from Marlon during the Desert Festival and a late chain of eradication goals all want the same week's work, which is the argument for choosing a target and staying with it rather than wandering.

Strategy

Pick the weapon for the behaviour rather than for its number. A broad sword swing covers a crowd of flyers, a club's weight knocks a charger out of reach, and a dagger's stabbing speed suits a single tough creature that needs holding in place. Carrying two of the three is worth a backpack slot.

Bring bombs even on a mining trip. They are the only answer to a downed mummy, they strip the shell off a disguised crab, they clear the rocks that give an armoured bug room to turn, and they do all of that while also opening the floor.

Use the reset. Leaving the mine and walking back in regenerates every floor, which turns a floor with a good pack on it into a renewable resource. The same trick works on the caverns, at the cost of starting the descent again.

Notes

Monsters on the farm are an option rather than an accident. The setting is on by default on the wilderness map and can be switched on or off anywhere by offering a Strange Bun at the dark shrine in the witch's hut. Farm creatures scale with the farmer's combat level, so a late-game farm gets serpents and golems rather than green slimes, and they pay a third of the usual experience. They count towards the guild's totals, while the quest journal and the order boards ignore them.

A Slime Hutch is friendly ground rather than a hunting ground, so what happens inside it stays off both the experience bar and the guild's wall.

One creature arrives without any setting at all. Each truffle a pig digs up carries a very small chance of standing up and running away, which is the only monster on the branch that a farm meets by accident on a sunny morning.
