monstats

monstats.txt is the primary definition table for every monster unit in D2R: enemy monsters, pets, and NPCs. Each row encodes the monster's identity, per-difficulty stats, AI behavior, resistances, skills, and treasure classes. With 752 rows × 273 columns, it's the widest table in the canonical data set.

Related: monlvl supplies the per-level scaling multipliers applied to the base stats here. superuniques overlays named unique champions on top of monstats base rows.

Key flags relevant for queries:

Per-difficulty stats

The same stat block repeats three times — once for each difficulty. Normal uses no suffix; Nightmare appends (N); Hell appends (H):

Resistances

Six resistance columns per difficulty (18 total):

Values ≥ 100 = immune. Negative values = extra vulnerability (Andariel has ResFi(H)=-50 — fire spells deal 50% bonus damage).

116 of 649 killable Hell monsters have ResFi(H) ≥ 100 (fire immune). This is why dual-element builds are standard for Hell progression.

Treasure classes

Eight TC variants per difficulty (24 total). For Hell:

The Desecrated/Herald columns are D2R-era additions for Terror Zone and Herald mechanics.

Worked example — Fallen (basic mob)

The Fallen family illustrates the per-difficulty level progression. The BaseId=fallen1 chain spans multiple variants (fallen1 through fallen5), each used in progressively higher-level areas.

SELECT Id, NameStr, "Level(H)", "MinHP(H)", "MaxHP(H)", "Exp(H)",
       "ResFi(H)", "ResCo(H)", "ResMa(H)",
       demon, killable, "TreasureClass(H)"
FROM monstats
WHERE Id = 'fallen1';

Worked example — Council Members (multiple variants, one name)

The three Council Member variants in Travincal show how Id is the true key while NameStr can be shared:

SELECT Id, "Level(H)", "MinHP(H)", "MaxHP(H)", "ResFi(H)", "ResLi(H)", "ResCo(H)",
       demon, MonType, "TreasureClass(H)", "TreasureClassDesecrated(H)"
FROM monstats
WHERE Id IN ('councilmember1','councilmember2','councilmember3');

All three share NameStr="Council Member" and MonType="councilmember", but councilmember1 is fire-immune while councilmember2/councilmember3 are lightning-immune. The superuniques table assigns two named Council members to each base type — Ismail Vilehand and Toorc Icefist spawn as councilmember1; Bremm Sparkfist and Maffer Dragonhand spawn as councilmember3. Querying NameStr alone would miss this resistance split; always filter on Id.

The TreasureClassDesecrated(H) column confirms these monsters have an elevated drop table when Travincal is the active Terror Zone.
