#Existing Yoma Variant Index

Contents

For the actual canon values, the co-08-02 Yoma Bestiary takes priority. This document is an index for quickly choosing an fc08-style interpretation and variant direction.

#Fiction Intro — A Bestiary With Many Margins

In the margins of the bestiary there was much writing smaller than the main text.

Beside oni it was written, "On the battlefield they eat commands before sake." Beside tengu it was written, "Distinguish the one who guards the mountain from the one who has lost it." Beside onryo it was written, "If the name does not match, the exorcism comes late."

A newly arrived scholar asked.

"Why was it not written in the main text?"

The old compiler answered.

"The main text leaves the name; the margin is corrected by those who survived. Yoma always change in the margins."

#Scent — The Index Is a Variant Table, Not a Fixed Table

A single yoma name crosses many eras and places. This index is a table for choosing "with what face to use this yoma" rather than "which yoma to use."

#Law — Full Variant Index

This table is an index for finding again, in fc08 style, all the yoma and yoma-related enemies listed in the co-11-14 Enemy Catalog. The values follow the canon; here we choose only the era face and the operational axis.

#Operation — Order of Variant Selection

Choose the canon stats.
Choose the place.
Choose one era variant.
Choose one desire.
Set the relationship with the Gate of the Spirit Realm.
Set one intervening faction.

Attach at most two variants at a time. For example, "Edo kaidan form + Named Onryo" is fine, but "Heian archetype + Edo kaidan form + modern-yoma form + reinforcement background" blurs the focus within a single event.
