setitems.txt defines every individual set piece in D2R — Civerb's Ward (the shield), Tal Rasha's Howling Wind (the amulet), Sigon's Visor (the helm), all the way to the post-launch Bane's Garments and Horazon's Splendor pieces. 141 rows total. Each row points at its parent set (sets index) and at its base item (weapons / armor / Misc.txt).

Three layers of stats per set piece

Every equipped set item layers stats from three sources. Understanding the layering is half the table:

Per-piece base stats — prop1..prop9 here. Always active, regardless of how many other set pieces are worn. Civerb's Ward always carries +15 defense and +15% block.
Per-piece "added" green-text bonuses — aprop1a/aprop1b .. aprop5a/aprop5b here. Activate as more other set pieces are equipped (the green text on the tooltip beyond the base stats).
Set parent's partial / full bonuses — PCode* / FCode* on the matching sets row.

The 9 base props plus 10 added "green" props (5 piece-count tiers × 2 slots), plus the parent set's 16 partials and 8 full-set slots, is why a fully-equipped set can stack a wall of green text in one tooltip.

What's in a row

The 100+ columns split into identity, drop eligibility, base stats, the added-bonus block, and visual/audio overrides.

Identity

Column	Meaning
`index`	Set piece's primary key — `Civerb's Ward`, `Sigon's Visor`.
`*ID`	Comment column — original row index, not read by the engine.
`*ItemName`	Comment column — display name for human reference.
`set`	Parent set (`sets` `index`). Connects this piece to its set-level bonuses.
`item`	Base item code (`weapons` `code`, `armor` `code`, or `Misc.txt`). `lrg` = Large Shield, `amu` = Amulet, etc.
`lvl`	Item level — monsters / containers must roll ilvl ≥ this for the piece to drop.
`lvl req`	Character level required to equip.

Drop eligibility

Same four-gate model as uniqueitems:

Column	Meaning
`disabled`	`1` = piece cannot drop. Empty / `0` = eligible.
`spawnable`	`1` = appears in standard gameplay.
`disableChronicle`	`1` = suppressed in Chronicles game mode (D2R-era).
`firstLadderSeason` / `lastLadderSeason`	Ladder-season window. Both empty = no ladder restriction. Same convention as `uniqueitems` and `runes`.
`DropConditionCalc`	Engine calc-DSL gate (rarely used).
`rarity`	Relative pick weight when multiple set pieces share a base.

Per-piece base stats — `prop1`..`prop9`

The familiar prop / par / min / max encoding, 9 slots here (uniqueitems extends to 12).

Columns	Meaning
`prop1`..`prop9`	Property code from `Properties.txt`. Empty = no stat.
`par1`..`par9`	Parameter (skill ID for `oskill`, blank for simple stats).
`min1`..`min9`	Minimum roll.
`max1`..`max9`	Maximum roll. `min == max` = fixed; `min < max` = roll range.

These are always active — the floor of stats the piece carries regardless of what else is worn.

Per-piece "added" bonuses — `aprop1a` through `aprop5b`

The set-piece tooltip's green text comes from this block. Indexed by piece count and slot letter:

Threshold	Slots	Activates when
`aprop1a` / `aprop1b`	2 stat slots	1 other set piece is equipped (total ≥ 2).
`aprop2a` / `aprop2b`	2 slots	2 others equipped (total ≥ 3).
`aprop3a` / `aprop3b`	2 slots	3 others (total ≥ 4).
`aprop4a` / `aprop4b`	2 slots	4 others (total ≥ 5).
`aprop5a` / `aprop5b`	2 slots	5 others (total ≥ 6 — full 6-piece set).

The a and b are two stat slots per piece-count threshold. Empty cells = no bonus at that piece-count tier. Combined across all 6 pieces of a 6-piece set, this block alone produces 60 stat-slots of green-text "as you wear more" bonuses — separate from the parent set's PCode* block in sets.

Visual & audio overrides

Column	Meaning
`chrtransform` / `invtransform`	Color shifts for character and inventory icon. The signature green color of set items comes from these.
`flippyfile` / `invfile`	Drop animation / inventory icon overrides.
`dropsound` / `dropsfxframe` / `usesound`	Audio overrides.

Economy

Column	Meaning
`cost mult` / `cost add`	Buy/sell/repair cost modifiers.
`add func`	Bonus distribution function (engine-internal).
`diablocloneweight`	DClone progress weight when sold to an NPC. Same mechanism as `uniqueitems`.

Worked example: Civerb's Ward

The shield piece of the 3-piece Civerb's Vestments Classic set:

Field	Value	Interpretation
`index`	`Civerb's Ward`	Display key.
`set`	`Civerb's Vestments`	Parent set.
`item`	`lrg`	Large Shield base.
`lvl` / `lvl req`	`7` / `9`	Drops at ilvl ≥ 7; equips at clvl 9.
`prop1` / `min1` / `max1`	`ac` / `15` / `15`	+15 defense (always active).
`prop2` / `min2` / `max2`	`block` / `15` / `15`	+15% block (always active).
`aprop2a` / `amin2a` / `amax2a`	`mana` / `21` / `22`	+21–22 mana when 2 others equipped (variable roll, 3-piece tier).
`aprop2b` / `amin2b` / `amax2b`	`res-pois` / `25` / `26`	+25–26 poison resist at the 3-piece tier.

The "+21-22 mana" green-text bonus is a variable roll — locks in at item generation, not at equip time. When reporting set-piece bonuses, always show the range, not the average.

Variable rolls

Many set pieces have min < max on at least one slot — most commonly on the per-piece base stats and the lower-tier added bonuses. The roll happens once at item generation; afterward the piece carries that fixed value forever.

Cross-references

sets — the parent set's partial- and full-set bonuses; this table's set column points there.
weapons / armor — item resolves into one of these (or Misc.txt for charms / jewels / amulets / rings).
itemtypes — base items inherit from itypes.
uniqueitems — same encoding (extended to 12 slots there).
itemstatcost — prop* ultimately resolves to stats here via Properties.txt.

Naming gotcha

setitems is the individual set pieces table — one row per wearable item. Set-level bonuses (the partials by piece count, the full-set stat block) are in sets. Don't confuse this with uniqueitems (the unique items) or magicprefix / magicsuffix (magic-item affix pools).
