Workers: They Mine While You Sleep

In TerraX, you do not swing the pickaxe yourself. Your workers do. Mining and harvesting run entirely through workers you assign to mine floors and groves, and they keep working whether you are online or asleep. Every new account starts with 2 free workers, which is enough to get your first expeditions running the moment you finish the tutorial. This guide covers how workers roll, what the exact pack odds are, how the pity system protects you, and how to build a workforce that earns around the clock.

Your First Two Workers

Before any theory, get your starters earning. Floor 1 of the mines, Surface Works, needs no water and no food, so your day-one workers can run it indefinitely on nothing but time. Send one worker mining and one harvesting, queue the longest expedition you are comfortable with, and let the game work while you learn the map. The materials from those first runs pay for everything that follows: your first real pickaxe, your first forge queue, your first market listing. Plenty of players never spend a thing and build entire operations from these two starters. The gacha exists to speed you up, not to unlock the game.

The Five Rarities

Workers come in five rarities: Common, Uncommon, Rare, Epic and Legendary. Rarity decides the stat ranges a worker can roll. A Common mining worker rolls between 1 and 4 mining yield, while a Legendary rolls between 22 and 35 before bonuses. The jump is real at every tier, but the two top rarities bring something extra: Epic and Legendary workers each roll one unique ability on top of their stats, and some of those abilities change how you play entirely.

The Four Specializations

Every worker rolls a specialization when summoned: Mining at 35%, Harvesting at 30%, Dungeon at 25%, and Versatile at 10%. Specialists get their primary stats multiplied by 1.5 after rolling, and their off-spec stats halved. That trade is steepest for Dungeon workers, who roll boosted combat stats and combat HP between 75 and 180 depending on rarity, but carry negative mining and harvesting stats in exchange. A Common dungeon specialist can lose 45 to 50 yield off-spec, while a Legendary only gives up 1 to 5. Versatile workers are the rarest roll and the safety pick: everything rolls from the base tables, the primary set still gets the 1.5 multiplier, and nothing goes negative.

The practical read: put Mining specialists on mine floors, Harvesting specialists in groves, Dungeon specialists on idle dungeon runs, and use Versatile workers to fill whichever slot is short. A dungeon specialist parked in a mine is wasting most of what makes it valuable.

Worker Packs and the Exact Odds

Additional workers come from Worker Packs in the store, and the odds are fixed per pack type. Standard packs only contain Common and Uncommon workers, weighted 60 to 40. Mystery packs carry the full spread: 65% Common, 25% Uncommon, 7% Rare, 2% Epic and 1% Legendary. Premium packs cut the low tiers out entirely and roll 60% Rare, 30% Epic, 10% Legendary. Legendary packs contain only the top two tiers at 70% Epic and 30% Legendary. Those are the real server-side weights, not marketing numbers, so you can plan your spending around them.

Which Pack Is Actually Worth Buying?

Run the numbers and the packs sort themselves. Standard packs can never roll above Uncommon, which makes them filler for empty slots and nothing more. Mystery packs give you a 3% combined shot at Epic or Legendary, fine for volume summoning on a budget. The honest jump is Premium: with a guaranteed Rare floor and a 40% chance at Epic or better, it is the first pack where every single pull matters. Legendary packs remove the floor question entirely, since every worker inside is Epic at minimum and 3 in 10 come out Legendary. If your goal is one great specialist rather than a big roster, save for the higher pack instead of spraying the lower ones. The math favors patience.

The Pity System

Bad streaks have a floor. TerraX tracks pity counters per account and checks them before every roll. If you go 10 summons without at least a Rare, your next pull is guaranteed Rare or better. Go 50 without an Epic and the next is Epic or better. Go 200 without a Legendary and the next one is Legendary, guaranteed. Counters reset when you hit the tier. If you are hunting a specific rarity, the pity thresholds tell you the worst case before you spend.

Unique Abilities Worth Chasing

Epic and Legendary workers roll one ability from their specialization pool, and the Legendary versions are dramatic. Mother Lode gives a mining worker a 20% chance to triple materials from any ore node. Overgrowth does the same for harvesting. Immortal Will lets a dungeon worker survive killing blows twice per dungeon and revive at 25% HP. On the Versatile side, Master of All removes the specialization penalty entirely, and Fortune's Favor gives a flat 20% chance to double all rewards from any activity. Two workers with identical stats can be worlds apart because of the ability line, so read it before you decide who stays on your payroll.

Reading the Overall Score

Every worker shows an overall score from 0 to 100. It is a weighted blend of the stats that matter for that worker's specialization, with a bonus for the ability. A mining worker is scored purely on mining yield and speed. A dungeon worker is scored across attack, defense, HP and dungeon stats. The score is a fast way to compare two workers of the same specialization at a glance, though for Epics and Legendaries the ability should still sway close calls.

Running Expeditions

Expeditions run from 1 hour up to 72 hours. Deeper mine floors demand better pickaxes and consume water and food each cycle, and water only comes from fishing, which is one of the ways TerraX ties its systems together. Every expedition also carries a 10% lucky find chance for a bonus Supply Lootbox. You start with one expedition slot per activity for free, and additional slots can be unlocked as you grow.

Feeding the Machine

Past floor 1, expeditions consume supplies each cycle, and the requirements climb with depth. Floor 2 drinks 2 water and eats 2 Herbs per cycle. Floor 3 wants 3 water and 3 Carrots. Floor 4, where Adamantium and Dragon Glass live, takes 4 water and a Walnut, and Walnuts are the rarest ingredient in the game. Water comes only from fishing, ingredients come from harvesting trees, and if you run short there is a cooked answer: the Witch's Cauldron, a 30-minute cook that stands in for floor 4 food. Tools take 2 durability per cycle too, so deep expeditions slowly chew through pickaxes. None of this is busywork for its own sake. It is the reason a player who only fishes can sell water to a player who only mines, and both walk away paid.

Here is the shift in thinking that separates veteran accounts from new ones: your character's level matters, but your roster is your real progression. Gear wears out and markets move, yet a well-built workforce of specialists earns every hour of every day, whether you logged in or not. The players at the top of the leaderboards are not the ones who grind hardest. They are the ones whose workers never stopped.
