Accommodations & Training

Accommodations are where your dwarves live — and, crucially, where their stats live too. Remember the core rule from the Overview: scalar stats live on accommodations, not on dwarves. You train a building, and every dwarf housed in it benefits from the higher stat at once. This page covers the eight accommodation types, the training-queue system, recovery rates, and the two special recovery buildings (Hospital and Tavern).

How Accommodations Work #

Each accommodation is the stat holder for one domain (extraction, research, market, etc.). It does two jobs simultaneously:

1. Holds a trainable stat for its domain, shared by all occupants. Higher stat = higher accommodationStat(domain) in the capability formula.
2. Passively recovers occupants’ Health and Fatigue via its comfortRate, boosted when the colony is well-fed.

A dwarf housed in a building matching its class gets the full domain stat; a dwarf of a non-matching class gets 0.5× the domain stat (but still full comfort/recovery). Universal buildings (Habitat, Hospital, Tavern) treat every class equally.

The Eight Accommodation Types #

Unlock conditions:

Training-cost themes match the domain: comfort uses Meals, extraction uses Iron, piloting uses Fuel, research uses Electronics, market uses Credits only. Credits are paid empire-wide; physical goods are paid from the local asteroid’s inventory.

A Garrison also trains a “defense” domain, but it is a defence building, not a standard accommodation — see Combat.

The Training System #

You raise a building’s domain stat by queuing training sessions. Each session runs for a duration, then awards XP; accumulated XP levels the stat up. This is shared progress — leveling the stat benefits all occupants, with no per-dwarf XP.

XP and Stat Formulas #

All accommodations share the same curve:

xpToLevel(n)    = 100 × n^1.6          # XP needed to reach stat level n
statMultiplier  = 1.0 + (statLevel × 0.08)   # the actual output multiplier
sessionDuration = 300 × statLevel^1.4  # seconds per training session (grows with level)

So every stat level adds +8% to that domain’s multiplier. A stat at level 5 is ×1.40; at level 10, ×1.80; at level 20, ×2.60.

Concrete Training Numbers #

Representative session lengths and XP awards (same for every accommodation type):

Sessions get longer and XP requirements climb steeply, so high stat levels are a genuine long-term investment.

Training Cost Scaling #

The base training cost in the table above is the cost at the lowest level. The actual cost charged when you queue a session scales with the stat level being trained:

actualCost = baseCost × (statLevel + 1)

For example, a Miner Quarters (base Iron 15) training its extraction stat at level 5 charges Iron 90 per session (15 × 6).

Training Queues #

Each accommodation has a limited number of concurrent training slots, which grows with the building level (not the stat level):

(The exact progression varies slightly per accommodation; specialist buildings tend to reach more slots faster than the Habitat.)

Upgrading the Building #

Building level is separate from stat level. Upgrading the building raises:

• Capacity — how many dwarves it can house (4 → 18 for standard accommodations).
• Training queue slots — how many sessions run at once.
• Comfort rate — passive Health/Fatigue recovery (for the Habitat and recovery buildings).

Upgrade time grows per level: baseUpgradeTimeSeconds × multiplier^level, where the base ranges from 45s (Habitat) to 180s (Science Dorm, Pilot Barracks, Hospital, Tavern) and the multiplier is 1.8–2.2. Upgrade resource costs climb steeply (e.g. a Habitat from Iron 200 at Lv1 to Iron 60,000 at Lv8).

Recovery (comfortRate) #

Every accommodation passively recovers its occupants. comfortRate is expressed as Health-per-hour and Fatigue-per-hour, multiplied by mealsMultiplier (typically ×1.5) when the colony is well-fed.

The Habitat has the strongest standard comfort curve, scaling from level 1 to level 8:

Specialist accommodations (Miner Quarters, Engineering Bay, etc.) provide a flat, modest comfort rate of about 6 Health / 10 Fatigue per hour at every level — they are built for work, not recovery. For real recovery, use a Habitat, Hospital or Tavern.

Hospital / Medbay (Recovery Specialist) #

The Hospital is where Injured dwarves heal. Key behaviours:

• Injured dwarves (status = injured) auto-route to benched slots — a separate pool from occupant slots — so a busy Hospital still treats the wounded.
• Recovery scales with Hospital level via: recoveryMultiplier = hospitalLevel × 0.25 + mealsFactor + aleBuffBonus (mealsFactor 1.0 well-fed / 0.5 starving; aleBuffBonus +0.5 when Healing Mead is active in the data tables).
• Severe-injury baseline recovery time drops sharply with level:

See Status & Needs for the full injury-severity table and the Downed → Rescued → Injured pipeline.

Tavern / Mead Hall (Morale & Ale Hub) #

The Tavern serves two roles:

1. Fatigue recovery — it clears Fatigue fast (no Health recovery at all). Its fatigue rate scales from 18/hr at Lv1 up to 100/hr at Lv6.
2. Morale + ale distribution — training its morale stat grants +5% global productivity per morale level, and it is where you serve ale buffs.

Tavern levels also increase ale storage per type (20 at Lv1 → 200 at Lv6) and an ale buff duration multiplier (×1.0 at Lv1 → ×1.75 at Lv6 in the data tables), so a higher-level Tavern both holds more ale and makes its buffs last longer.

Unconfirmed: the Tavern’s aleBuffDurationMultiplier and the data-table ale effect magnitudes are first-pass and differ from the live buff durations applied by the simulation. See Ale & Potions for the authoritative effects.

Training Strategy #

• Level the buildings your crew actually fills. A high extraction stat is wasted if your Miner Quarters is half-empty — and a full Quarters makes every extraction level pay off many times over.
• Match classes to buildings. Non-matching classes only get 0.5× the domain stat, so house miners in Miner Quarters, scientists in Science Dorms, etc.
• Keep Credits and the themed resource flowing — training is charged up-front per session and scales with stat level, so a deep training queue is a real resource sink.
• Don’t neglect the universal buildings. Habitat comfort, a leveled Hospital, and a morale-trained Tavern keep the whole colony fed-fast, healed-fast and buffed — multiplying the value of every specialist building you own.
