Automata
Forge robots that mine for you while online — buy, upgrade, activate, and stack prestige multipliers.
Automata are robots you forge to mine on your behalf. Each robot ticks every second and deposits its output straight into your wallet — no manual collecting required, though you can summon a summary anytime. The system blends three currencies (Auctoritas, Civitas, Aureus) with exponential cost scaling, upgrade levels, an active-robot bonus, and a prestige multiplier. Stack it all together and a maxed forge is one of the strongest passive income engines in the empire.
Robot Types
There are three tiers of automaton, each gated behind a permission node and a different currency. Higher tiers produce far more per robot but cost a much rarer currency to buy and upgrade. All three are defined in automata.yml, so the catalog can grow.
| Tier | Currency | Base Production | Base Cost | Max Level |
|---|---|---|---|---|
| Basic (Auctoritas Automaton) | Auctoritas | 1.0/s | 10,000 tokens | 100 |
| Advanced (Gemma Automaton) | Civitas | 5.0/s | 100,000 beacons | 50 |
| Elite (Fragmentum Automaton) | Aureus | 25.0/s | 1,000,000 gc | 25 |
The displayed names follow Roman numeral tiers (Auctoritas Automaton I-IV, Gemma Automaton I-IV, Fragmentum Automaton I-IV) based on the digits in the robot's config key.
How Production Works
Every second, a background task loops over each online player's robots and credits the appropriate currency directly to their balance (reason robot_auto). The per-second production for a single robot type is computed as:
production = baseProduction × count × levelBonus × prestigeBonus × activeBonus
Where each multiplier stacks:
- levelBonus —
1.0 + (level × 0.1), so each upgrade level adds +10%. - prestigeBonus —
1.0 + (prestigeLevel × 0.05), so each prestige adds +5%. - activeBonus — 1.5× (i.e. +50%) if this is your currently active robot type, otherwise 1.0.
Example: 10 Advanced robots at Level 5 with Prestige 4 and the Advanced robot set active would produce 5.0 × 10 × 1.5 × 1.2 × 1.5 = ~135 Civitas/second.
Cost Scaling
Robots use classic exponential cost scaling — every robot you own makes the next one more expensive. The cost for the next robot of a type is:
cost = baseCost × 1.15^ownedCount × (1.0 + prestigeLevel × 0.05)
The 1.15× exponent compounds fast: the 10th Basic robot costs roughly 4× the first, the 20th roughly 16×. The prestige multiplier nudges everything up by 5% per prestige level, so high prestiges pay a slight premium — but they also produce more thanks to the prestige bonus. Upgrades scale even harder: upgradeCost × 1.5^currentLevel × (1.0 + prestige × 0.05), so each level costs 50% more than the last.
The Active Robot Bonus
You can only have one robot type active at a time. Activating a type gives it a permanent +50% production bonus (the 1.5× active multiplier) for as long as it's active. Shift-click a robot in the forge menu to toggle it active or inactive — the active type glows with an enchant shimmer and shows a ▶ marker in its name.
Pick the type that produces the currency you care most about. Most players keep their highest tier active, but if you're starved for Auctoritas it can be worth activating the Basic line instead.
The Forge Menu
Open the Legion Automata Forge with /automata. The 54-slot GUI has your robot types up top and control items in the bottom row:
| Click Action | Effect |
|---|---|
| Left-Click | Purchase one robot of that type. |
| Right-Click | Upgrade that robot type by one level. |
| Shift-Click | Activate (or deactivate) that robot type as your active robot. |
Each robot item shows live stats: current level and max, owned count, per-second production, currency, the next purchase cost, and the next upgrade cost. The Ledger book item summarises your total robot count, total production, active robot, and remaining slots.
Collecting and Offline Behavior
Production is credited in real time by the per-second task — your balance updates automatically as you play. The Collect Production chest item (and the underlying collectProduction call) is a display-only summary of how much was produced since your last check; it does not credit currency a second time. Think of it as a receipt, not a claim.
Robots only produce while you are online. The per-second task only iterates over online players, so logging off pauses production entirely — Automata are not an offline income source. For passive offline gains, look at the Auto Miner instead.
Slots and Bulk Buying
You can own up to 100 robots total across all types. The ledger shows your remaining slots out of 100. The Bulk Purchase hopper item hints at /robot bulk <type> <amount>, which buys between 2 and 64 robots of a type in a single transaction — handy when you're pouring a windfall into a fresh tier. Bulk purchases still respect the 100-robot cap and sum the exponentially-scaled costs.
Effects Toggle
Prefer a quieter screen? The Effects lever item (or /automata effects) toggles the flame particle that spawns above players with an active robot. It's purely cosmetic and per-player — your production is identical either way. Low-end-client players often turn it off to save frame rate.
Command Reference
| Command | What it does |
|---|---|
/automata | Open the Legion Automata Forge GUI — buy, upgrade, activate, collect. |
/robot | Alias for the automata menu. |
/robot bulk <type> <amount> | Buy 2-64 robots of a type in a single transaction. |
/automata effects | Toggle the flame visual effect on active robots. |
PlaceholderAPI hooks are also available: %imperiummc_robot_total_count%, %imperiummc_robot_total_production%, %imperiummc_robot_active%, %imperiummc_robot_slots_remaining%, and %imperiummc_robot_max_slots%.
Tips
- Concentrate on one tier. Spread thin across all three and you lose the active bonus on two of them. Pick a currency goal and pour everything into that tier.
- Upgrade before buying more. Past ~15 robots the 1.15× exponent makes the next robot pricier than a level — and levels are +10% production flat across your whole fleet.
- Prestige before pushing hard. The +5% per prestige applies to both production and cost, but production compounds across every robot and level you own.
- Stay online. Automata only tick for online players. Long AFK sessions earn nothing from robots — combine with a Token Passive pet if you want AFK income.
- Use bulk buys on windfalls. Got a 500k Auctoritas crate drop?
/robot bulk basic 30dumps it straight into your forge. - Watch the Ledger. The total production figure is the single best stat for tracking your passive income growth over time.
A maxed Automata forge — 100 robots, all at max level, with the right type active and a high prestige — can out-earn active mining for some currencies. It is the closest thing Imperium has to a "money printer," and it rewards patient, focused investment.
