#Western · Chinese · OSR Yoma Conversion (Yoma Conversion) — Section Index

Contents

#Identity

Data-convert Western monsters · Chinese yokai · OSR monsters into the Konsei Reiyotan yoma template (Mob/Minion/Veteran/Elite/Lord). Beyond simple cataloguing, it provides a conversion guide — teaching the GM the pattern that "any monster can be turned into the core format."

IP safety follows the 99-07 guide (public domain uses original names, media origins use altered names).

#Design Goals

120~180 yoma conversions total.
Distribution by cultural sphere:
Western monsters 50~70 types
basic humanoids (goblin · orc · troll · kobold · ogre)
undead (zombie · wight · lich · vampire · banshee · specter)
magical beasts · monsters (unicorn · griffin · chimera · pegasus · hydra · basilisk)
Western dragons 5~8 types
fey · fairy
Western demons · angels
Chinese yokai · gui · xian 30~40 types
yokai (nine-tailed fox national versions · yaksha king · nue · Shanhaijing · jiangshi)
gui (gaki · vengeful ghost · water ghost)
xian · gods (Eight Immortals · Guan Yu deification · Guanyin · Four Seas Dragon Kings)
OSR-unique 10~15 types — rust monster · gelatinous cube · mind flayer (proxy) · beholder (proxy)
Cthulhu line 5~8 types (optional) — shoggoth · nightgaunt · Dagon
Conversion guide 1 file — D&D HD → yoma grade, AC → Defense, attribute preservation, special-ability reinterpretation.
Conversion examples — 2~3 complete conversion examples per file (original values → Konsei Reiyotan values comparison table).

55-14	(guide) yoma squad composition	—	outside the conversion count. Scenario GM guide. Compatible with core 06-06 squad rules.
Total	—	58	(old 61 - 3 core same-name collisions)

#Grade Distribution (Updated After Collision Integration)

Mob: 7 / Minion: 21 (-1: gaki) / Veteran: 11 (-1: nue) / Elite: 14 / Lord: 4 (-1: nine-tailed fox) / Divine Item: 1.
Total: 58 (old 61 - 3).

#Grade-Name Notation Policy

This expansion uses the suffix "級" forms "Mob-grade/Minion-grade/Veteran-grade/Elite-grade/Lord-grade" as the base notation. Core 08-02 uses suffixless forms ("Mob", "Minion", "Veteran", "Elite", "Lord") in table layouts, and core general body text mixes both notations — "級"-suffix and suffixless are equally consistent. Some files (55-11 · 12 OSR · Cthulhu) adopt the suffixless notation closer to the core 08-02 table layout. The GM of this expansion may use either notation.

#Core Consistency

This expansion 55 fully complies (100%) with the core 08-02 yoma compendium standard stat block + this expansion's 00-05 own mechanics 0.9.3 settled rules:

enforce the core standard stat-block format (name · grade · Wounds · Defense · Energy · 6 attributes · 4 technique slots · special · Domination).
limited to 6 attributes (Courage · Finesse · Physique · Wisdom · Presence · Fate). Invented attributes forbidden.
check formula 2d10 + attribute + proficiency ≥ Defense. Abstract "attack +N" forbidden.
damage unit = Wounds (00-05 §3).
recovery effect = "[upkeep] recover Wounds +N" (00-05 §3).
Multiattack = cap of 2 per round (00-05 §7).
attack +5 or more · instant death = 2+ limiting conditions (00-05 §10 · 15).
morale → Cohesion (00-05 §12).
madness · trauma = 30-10 dependency stated.
non-corporeal · [Incorporeal] attack unified rule mandatory (08-02 §non-corporeal unified rule).
avoid core same-name yoma collisions (integration of nine-tailed fox · nue · gaki).
remove D&D-style Critical Hit notation ("1d10 = 9-10"). Use core Critical Hit (2d10 double) or 00-05 §15 Critical Expansion.

#Friendly NPCs

5 entities (unicorn · pegasus · seraph · Guanyin · golden dragon, etc.): usually friendly, can be made hostile.

#Differentiation from the 1st Expansion

Core Japanese yoma + 1st-expansion 25 hell yoma + this expansion's 58 conversions = can be used in integration. See the 99-04 integration index.

#IP Safety

All media-origin conversions use altered names. Follows the 99-07 IP guide.

"Every monster is translatable text. The rules are the dictionary."
