#Core Ledger Sheet — Harvest · Storage · Spoilage · Consumption Log

Contents

Scene Tool — ex1 Core Economy GM ledger. This document is the actual record-keeping sheet for the Yoma Core Economy. Barrier HP and core inventory management are maintained as-is; spoilage is handled not as individual-core d100 rolls but as 1 weekly spoilage event.

#§ Usage

#When to Use

Before the session (5 min): Check last week's inventory. Note expected harvests and consumption for this week.
During the session (as needed): Enter harvests when the expedition returns. Enter consumption when cores are injected.
After the session (5 min): Enter the final inventory for this week and the weekly spoilage event result.

#How to Use

Enter values by week in the 3-stage inventory table.
Record expedition harvests in the harvest log.
Record Barrier injections and facility fuel use in the consumption log.
Roll the weekly spoilage event 1 time only and apply the result.
Record lower-to-higher conversion work in the core synthesis log.

#Who Uses It

GM only. However, qualitative inventory status may be disclosed to players.
Examples: "We have many unstable cores but no stable cores," "Only a single high-purity core remains."

#§ Core Stage Summary

───────────────────────────────────────────────────────────────────────
 Stage       │ Injection Effect │ Storage Cap │ Harvest Source
───────────────────────────────────────────────────────────────────────
 Unstable core  │ Barrier HP +10  │ 20 cores  │ Minion- and Veteran-grade yoma
 Stable core   │ Barrier HP +30  │ 8 cores  │ Elite-grade yoma, core synthesis
 High-purity core │ Barrier HP +60  │ 3 cores  │ Lord-grade yoma, high-grade synthesis
───────────────────────────────────────────────────────────────────────

Degradation path:
 High-purity → Stable → Unstable → Spoiled (invalid)

Core synthesis:
 3 unstable cores → 1 stable core
 3 stable cores  → 1 high-purity core

Week: ____  Date: ____________

Storage environment:
 □Ordinary container(-1) □Brass jar(0)
 □Dedicated Barrier storehouse(+1) □Spirit-vein water-vein storehouse(+2)

Roll:
 d10 _____ + storage modifier _____ = final _____

Result:
 □1 Major spoilage
   The oldest high-purity/stable core drops by 1 stage.
   If none exist, determine the number of unstable cores that spoil with d10:
    1-5: 1 core / 6-8: 2 cores / 9-10: 3 cores
 □2-3 Minor spoilage
   The oldest core drops by 1 stage.
 □4-10 Stable
   No change.

Post-update inventory:
 Unstable cores: ____ Stable cores: ____ High-purity cores: ____

 Check: 2d10 + Wisdom + Herbalism >= 15
 Failure: 1 input core is lost
 Critical failure(1-1): all cores spoil

#§ Post-Session Check

□ Applied this week's harvest log to the inventory table.
□ Applied this week's consumption log to Barrier HP.
□ Handled any cores exceeding the storage cap.
□ Rolled the weekly spoilage event 1 time.
□ Recorded the starting inventory for next week.
