ID tables
The mod format refers to game content by number. These tables list every numeric ID the base game defines, with the name each number refers to — so a line like power 6 2 can be read without digging through the PDF.
Monsters
1851 entries
Every unit and commander in the base game, numbered from 0.
Weapons
935 entries
Weapon and attack numbers, from Fist upwards.
Items
287 entries
Magic item numbers used by item and reward commands.
Rituals
583 entries
Ritual numbers — numbering starts at 1, not 0.
Ritual schools
65 entries
Ritual school (pow) numbers with their names, from Necromancy to the Raksharaja.
Spell paths
68 entries
The combat casting paths a spellweapon command refers to — separate numbering from the ritual schools.
Combat spells
1029 entries
Every combat spell of every path with level, range, damage and area — spells are not moddable, but spellweapon lines are read with this table.
Terrains
356 entries
Terrain and location numbers used by map and event commands.
Terrain groups
115 entries
The negative terrain numbers — each stands for a whole set of terrains, from -1 (anywhere) down.
Classes
30 entries
The playable classes — numbering starts at 1, not 0.
Resources
19 entries
Resource numbers — the number is the position in the game's resource list.
A school argument outside the ritual schools table is most likely not a base-game school — the data comes from an older game version, so newer additions may be missing.
