Sarcophagus Guide

Sarcophagus Guide

This guide covers the Goa'uld sarcophagus as a player system: unlock flow, intake rules, treatment behavior, power planning, and side-effect management.

For broader unlock flow, see Research and Progression.
For power backbone planning, see Power, Shields, and ZPM Infrastructure.
For symbiote/Tretonin interactions, see Symbiotes and Prim'ta.

At a Glance

• Goa'uld sarcophagus is an endgame medical structure with very high burst power draw.
• You must analyze a recovered sarcophagus artifact before the research can be completed.
• Non-guests must be assigned to a sarcophagus to use it.
• Missing-part regrowth needs separate research (sarcophagus regeneration).
• Full treatments can apply sarcophagus high and sarcophagus addiction.
• Power loss mid-cycle interrupts treatment and ejects the patient.

Unlock Path

1. Complete Goa'uld tech (Rimgate_GoauldBasic).
2. Recover a sarcophagus artifact and analyze it:
   • analysis time: 10 hours
   • catastrophic failure chance: base 25% (reduced by higher Intellectual)
   • the analyzed artifact is consumed either way
   • catastrophic results do not unlock the research, so you need another artifact copy
3. Complete sarcophagus research (Rimgate_GoauldSarcophagus, base cost 3500).
4. Optional upgrades:
   • sarcophagus regeneration (Rimgate_SarcophagusBioregeneration) for missing-part regrowth
   • sarcophagus calibration (Rimgate_SarcophagusOptimization) for major power-efficiency gain (includes a techprint gate)

Who Can Use It

• Humanlikes only (no animals/mechs; non-entitled mutants are excluded).
• Medical care cannot be set to No care.
• Sarcophagus must be powered, reachable, not burning, not broken, and not already occupied.
• Allow guests, Allow slaves, and Allow prisoners toggles are enforced.
• Non-guests must be assigned to that sarcophagus.
• A pawn can only be assigned to one sarcophagus at a time.
• Ideology edge case: if a pawn's ideology requires scars or blindness, they may not treat those conditions as valid reasons to enter.

What It Treats

Base behavior includes:

• Tendable injuries and diseases.
• Chronic and permanent conditions (unless explicitly excluded).
• Addictions (except excluded addiction hediffs).
• Immunizable illnesses and other serious medical states.
• Blood loss is stabilized immediately during diagnosis.

Advanced behavior:

• Missing body-part regrowth only activates after sarcophagus regeneration.

Notably excluded by default:

• sterilized
• childbirth labor hediffs
• sarcophagus high
• sarcophagus addiction
• tretonin addiction
• Krin'tak sickness
• pouch degeneration
• symbiote withdrawal

Treatment Cycle

1. Intake:
   • patient can self-seek treatment
   • doctors/wardens can auto-rescue/carry valid patients
   • a manual Rescue to sarcophagus float-menu option is also available
2. Diagnosis:
   • default max time: 15 seconds, scaled by body size
3. Healing:
   • default max per-hediff time: 30 seconds, scaled by body size and severity
   • each treatable hediff is processed in sequence
4. Discharge:
   • normal completion restores saved needs and applies full post-treatment effects
   • interruption (power loss/abort) ejects patient with interrupted outcome

While in active treatment, food/thirst/hygiene/bladder needs are held full and restored on discharge.

Power and Stability

• Default power profile:
  • 500W idle
  • 4000W diagnosis
  • 8000W healing
• With sarcophagus calibration (default reduction factor 0.65):
  • diagnosis drops to 2600W
  • healing drops to 5200W
• Any power outage during treatment interrupts the cycle and ejects the patient.

Practical rule: treat sarcophagus lines as protected critical infrastructure, not overflow load.

Side Effects and Dependency Loop

On normal completion, sarcophagus use can apply:

• sarcophagus high
• sarcophagus addiction
• sarcophagus chemical-need increase

Additional effects:

• Existing sarcophagus addiction can intensify with repeated use.
• Addicted pawns may seek treatment even when lightly injured, driven by chemical need.
• Biological age is pushed back toward adult minimum age.
• With Biotech active, age-reversal demand is reset and hemogen/wraith essence genes are topped up.

Important: the sarcophagus does not clear sarcophagus addiction or tretonin addiction.

Automation and Interaction Rules

While a patient is inside a powered sarcophagus:

• doctors/wardens skip normal feeding and fluid-administer jobs
• scheduled surgeries are blocked
• manual tend/strip/arrest/carry float-menu options are suppressed

If you need surgery or manual tending, eject first.

Common Mistakes

• Forgetting assignment rules and expecting unassigned colonists/prisoners to use it.
• Enabling prisoner/slave usage but not toggling Allow prisoners / Allow slaves.
• Running sarcophagus cycles on unstable grids and causing repeated interruption ejections.
• Treating it as an addiction cure for sarcophagus/Tretonin dependencies.
• Ignoring its 80000 wealth hit when raid pressure is already high.

Strategy Checklist

• Put the first sarcophagus on a protected, redundant power lane.
• Use high-Intellectual analysts for artifact study to reduce catastrophic loss risk.
• Assign a small priority pool (critical combat pawns, key specialists) before opening wider access.
• Get sarcophagus regeneration before relying on it for limb-loss recovery.
• Get sarcophagus calibration before scaling usage across many pawns.
• Pair usage policy with your drug/medical doctrine and tune values in Mod Settings Reference.
