superuniques.txt defines the named, fixed-position unique monsters that spawn in specific locations every game — Rakanishu in the Stony Field, Pindleskin at Nihlathak's Temple entrance, the Council members in Travincal, Nihlathak in his temple. Each row layers a unique-mod overlay onto a base monstats row plus an escort-pack size and difficulty-keyed treasure tables.

67 rows total (66 named + 1 blank placeholder). The five act bosses (Andariel, Duriel, Mephisto, Diablo, Baal) are not in this table — they live directly in monstats with the boss=1 flag set. See Where the act bosses live below.

What's in a row

The 23 columns split into six groups.

Identity

Column	Meaning
`Superunique`	Unique name ID for the Super Unique monster — the row's primary key (`Rakanishu`, `Council Member 3`).
`Name`	String-table key for the monster's display name. Usually matches the in-game name (Bishibosh → "Bishibosh"), but not always: Hephasto the Armorer's row has `Name=The Feature Creep` — a developer codename that the string tables map to his real display name.
`hcIdx`	Unique numeric ID for the Super Unique monster. The existing IDs are hardcoded into specific scripts that reference these monsters by ID — changing one would break the script.
`MonSound`	Sound-profile override referencing `MonSounds.txt`. Set on only 3 rows: The Countess (`countess`), The Smith (`smith`), Hephasto (`smithdemon`). Empty rows inherit the base monster-class sounds.

Base monster reference

Column	Meaning
`Class`	The `monstats.Id` the unique is built on. Rakanishu → `fallen2`, Pindleskin → `reanimatedhorde5`, Coldcrow → `cr_archer1`. The unique inherits all stats, AI, drops, and animations from this row, then overlays its own modifiers.

62 of 66 named rows reference distinct Class values; the 4 collisions are Council members (Ismail and Toorc share councilmember1; Bremm and Maffer share councilmember3).

Unique-monster mods

Column	Meaning
`Mod1`, `Mod2`, `Mod3`	Up to 3 monster modifiers to assign to the unique. Each value is an `id` from `MonUMod.txt` (where the actual mod definitions live — Lightning Enchanted, Multishot, Magic Resistant, the various aura overlays, etc.).

Distribution: 62 of 66 named rows use Mod1; 44 use Mod2; only 4 use Mod3 — the third slot is reserved for the rare cases where a superunique needs three modifiers. The four three-mod superuniques are:

Name	Class	`Mod1` / `Mod2` / `Mod3`
Boneash	`skmage_pois3`	8 / 5 / 18
Ancient Kaa the Soulless	`unraveler3`	25 / 5 / 17
Lord De Seis	`doomknight3`	5 / 30 / 24
Vinvear Molech	`succubuswitch2`	8 / 5 / 18

Escort pack

Column	Meaning
`MinGrp`	Minimum number of base-class minions that spawn alongside the unique.
`MaxGrp`	Maximum number of minions. Must be `≥ MinGrp`. If strictly greater, the engine rolls a random count in `[MinGrp, MaxGrp]`; if equal, the count is fixed.
`AutoPos`	`1` = unique spawns randomly within a radius of its designated position. `0` = unique spawns at the exact coordinates of its designated position.

Spawn behavior

Column	Meaning
`Stacks`	`1` = the unique can spawn more than once per game session; `0` = only one instance per game.
`Replaceable`	`1` = the room where the unique spawns can be substituted during level-preset generation; `0` = the room is static and cannot be replaced.

Cosmetic

Column	Meaning
`Utrans`, `Utrans(N)`, `Utrans(H)`	Color-transform palette index per difficulty. Special values: `≥30` defaults to `2` (the monster's default palette shift); `0` or empty rolls a random palette index. Otherwise the literal value selects the palette.

Treasure classes

Column	Meaning
`TC`, `TC(N)`, `TC(H)`	Treasure class drop table per difficulty. References `TreasureClassEx.txt`.
`TC Desecrated`, `TC(N) Desecrated`, `TC(H) Desecrated`	Treasure class used when the area is terrorized (i.e. the active Terror Zone for the current hour). The engine column name `Desecrated` is synonymous with the in-game term terrorized — they refer to the same Terror Zone mechanic. The terrorized variant boosts the drop bracket, which is why Terror Zones drop higher-tier loot than the area's base difficulty would normally allow.

The Desecrated columns are D2R-era additions for Terror Zone support and aren't documented in the legacy LoD reference. Locbones predates them.

Worked example: Rakanishu

The classic Act 1 lightning-enchanted Carver pack leader in the Stony Field:

Column	Value	Notes
`Superunique`	`Rakanishu`	Row key.
`Name`	`Rakanishu`	String-table key; happens to match the display name.
`Class`	`fallen2`	Inherits Carver stats + Fallen AI.
`Mod1` / `Mod2` / `Mod3`	`17` / `6` / `0`	Two mods overlaid on the base Carver. Mod-ID meanings live in `MonUMod.txt`.
`MinGrp` / `MaxGrp`	`8` / `8`	Always spawns with exactly 8 minion Carvers — the iconic "Rakanishu and his pack" (no random range, since Min == Max).
`AutoPos`	`0`	Spawns at exact coordinates in the Stony Field, not within a radius.
`Stacks`	`0`	Only one Rakanishu per game.
`Replaceable`	`1`	The room containing him can be substituted during level-preset generation.
`Utrans*`	`29` / `29` / `29`	Palette index 29 across all three difficulties.
`TC` / `TC(H)` / `TC(H) Desecrated`	`Act 1 Super B` / `Act 1 (H) Super B` / `Act 1 (H) Super B Desecrated`	Standard Act 1 Super B drop bracket; the Desecrated variant kicks in when the Stony Field is the active Terror Zone.

The engine uses Class=fallen2 to pull base stats from monstats, scales them through monlvl at the area's mlvl, applies the two MonUMod overlays, spawns 8 escort Carvers at the exact Stony Field coordinates, and rolls drops from the appropriate Super B treasure class for the current difficulty (and from the Desecrated variant if the area is terrorized).

Where the act bosses live

The five act bosses — Andariel, Duriel, Mephisto, Diablo, Baal — are not in this table. They're standalone entries in monstats with boss=1, custom AI, and dedicated treasure classes; the superunique data shape is wrong for them (no escort pack, no shared base, no Replaceable substitution).

Cross-references

monstats — Class references monstats.Id. Stats, AI, drops, and animations all inherit from there.
monlvl — the level-scaling multipliers applied on top of the inherited monstats values, per the area's MonLvl(diff).
levels — assigns superuniques to map positions; the area's MonLvl(diff) is what determines the unique's effective level.
MonSounds.txt — defines the sound profiles that MonSound references.
MonUMod.txt — defines the meanings of Mod1/Mod2/Mod3 numeric IDs.
TreasureClassEx.txt — the TC columns reference treasure-class names defined here.
