Requires Iskandert's Utilities 3.4.0.0.0 or newer (not present in earlier mod releases).

Suspicious Delivery (iska_utils:suspicious_delivery) is a consumable item that grants a random reward when used. Pack developers configure the loot table via datapack; obtaining (Wandering Trader drop and trade) is handled by the mod.

Tooltip lines (lang keys):

• tooltip.iska_utils.suspicious_delivery.obtaining0 — dropped by Wandering Trader
• tooltip.iska_utils.suspicious_delivery.obtaining1 — traded by Wandering Trader
• tooltip.iska_utils.suspicious_delivery.obtaining2 — optional Mimic line (only when Artifacts is loaded)

• Use (right-click): server picks one weighted entry from the loaded definition, runs all actions in that entry’s do list, then consumes one item from the stack.
• Shift+use (sneak + right-click): 3.8.0.0.0+ — opens packages in a loop while the stack still has items. After each roll, if the entry has quick_open: true, continues; if quick_open is false or omitted, opens that package once and then stops (remaining stack is kept).
• Items are dropped at the player’s position (drop action). Messages use the same message format as Command Items.
• If no definition is loaded or all weights are zero, the item is still consumed but nothing is granted.

Place JSON under:

data/<namespace>/load/iska_utils_suspicious_delivery/

Or a flat file under data/<namespace>/load/ with "type": "iska_utils:suspicious_delivery" (routed by type).

Reload: /iska_lib_dev reload or /reload.

Important: Only one definition file is kept at runtime — the last matching file in datapack load order replaces the entire table (entries are not merged across files). Use a single file or namespace priority you control.

{
  "type": "iska_utils:suspicious_delivery",
  "overwritable": true,
  "entries": [
    {
      "weight": 1,
      "luck": 0,
      "do": [
        { "drop": "iska_utils:drop_of_entropy" }
      ]
    },
    {
      "weight": 3,
      "luck": 0,
      "do": [
        { "message": {
          "target": "@s",
          "distance": 0,
          "color": "#FFD700",
          "in": "action_bar",
          "text": "message.suspicious_delivery.mining_equitizer"
        }},
        { "drop": "iska_utils:mining_equitizer" }
      ]
    }
  ]
}

Same action types as command items (execute, message, delay, if, per-action stages). Suspicious Delivery also supports:

item: delete/consume/... actions are ignored with a log warning.

Same layout as Factory: one input slot (Suspicious Delivery) and a 9×3 output grid per page (up to 27 visible entries per JEI page; extra pages if needed).

• show — one grid slot per entry; if do has several drop actions, they alternate in that same slot (addItemStacks).
• hidden — not shown in the grid; weight still counts in the percentage denominator.
• mask — wins over drops; that slot always shows iska_utils:suspicious_delivery_undefined.

Per-slot tooltip: 30.0% (one decimal) and optional luck: <value> when luck ≠ 0. Percentages use the eligible pool for the current player context (mods always; stages on SP / integrated server). JEI refreshes when opening the category or the Suspicious Delivery GUI — no /reload required after stage changes.

While opening a Suspicious Delivery, the player’s Luck and Bad Luck effects adjust the weighted roll:

• Net = (LUCK level) − (UNLUCK level) where level = amplifier + 1 (0 if absent).

Fortune (net ≥ 0):

Unluck (net < 0): symmetric with effective = −net, rerolling while luck > 0 and toward luck ≤ −1000 / ≤ −10000.

If no entry in the pool reaches the forced threshold, the current pick is kept (debug log).

{
  "weight": 2,
  "luck": 0,
  "jeimode": "show",
  "do": [
    { "message": { "target": "@s", "in": "action_bar", "text": "message.iska_utils.suspicious_delivery.nested" } },
    { "drop": "iska_utils:suspicious_delivery" }
  ]
}

Use these exact execute strings (do not alter NBT or selectors):

{
  "weight": 3,
  "luck": -10,
  "jeimode": "mask",
  "do": [
    { "message": { "target": "@s", "in": "action_bar", "text": "message.iska_utils.suspicious_delivery.bomb_tickle" } },
    { "delay": 20 },
    { "message": { "target": "@s", "in": "action_bar", "color": "#FF0000", "text": "message.iska_utils.suspicious_delivery.bomb_alarm" } },
    { "execute": "summon tnt ~ ~ ~ {fuse:5000, Tags:[\"fake_tnt\"]}" },
    { "delay": 100 },
    { "execute": "kill @e[type=tnt,tag=fake_tnt]" },
    { "message": { "target": "@s", "in": "action_bar", "text": "message.iska_utils.suspicious_delivery.bomb_clock" } },
    { "drop": "minecraft:clock" }
  ]
}

Requires Iskandert's Utilities 3.8.0.0.0 or newer.

• Normal use: one package per click (unchanged).
• Shift+use: server opens packages in a loop while the stack still has items:
  1. Weighted roll → run do[] → consume 1 item.
  2. If the winning entry has quick_open: true and the stack is not empty → repeat.
  3. If quick_open is false or omitted → open this package, then stop (remaining stack is kept).

Pack authors should set "quick_open": true on instant rewards (drops, messages) and omit it or set false on entries with delay, execute, or other long scripts (e.g. fake TNT bomb).

Example — instant reward (bulk-eligible):

{
  "weight": 100,
  "luck": 500,
  "quick_open": true,
  "do": [{ "drop": "iska_utils:chosen_cheese" }]
}

Example — bomb (not bulk-eligible; default quick_open: false):

{
  "weight": 50,
  "luck": -10,
  "jeimode": "mask",
  "do": [
    { "message": { "target": "@s", "in": "action_bar", "text": "message.iska_utils.suspicious_delivery.bomb_tickle" } },
    { "delay": 20 },
    { "execute": "summon tnt ~ ~ ~ {fuse:5000, Tags:[\"fake_tnt\"]}" }
  ]
}

Built-in data/iska_utils/load/iska_utils_suspicious_delivery/suspicious_delivery.json includes:

• drop_of_entropy (luck: 10000) — only when Artifacts is not loaded (mods: [{ "mod": "artifacts", "is": false }])
• cursed_key (luck: 10000) — only when Artifacts is loaded (mods: [{ "mod": "artifacts", "is": true }]); same weight slot as Drop of Entropy, mutually exclusive
• Artifacts luck 100–1200 (weight 100, cursed_candle 75); nested 85; bomb (mask) 50; Arcane Dictionary 50 / luck: 30; entropy 30 (rarest by weight among scripted outcomes)
• Nested Suspicious Delivery (luck: 0, drops another suspicious_delivery)
• Bomb entry above (luck: -10, jeimode: mask)

Override by adding your own file in a datapack with the same type; ensure it is the winning file if multiple packs define one.

Add keys under assets/<namespace>/lang/ for any message actions, for example:

"message.suspicious_delivery.mining_equitizer": "Mining Equitizer found"

Entry-level gates use the same field names as Command Items: mods, mods_logic, stages, stages_logic. Entries are always loaded at /reload (no load-time stripping when a mod is missing).

For DEF_*, stages[] / mods[] are an indexed pool. Inside each if block, conditions / mod_conditions list indices (same layout as command items). Multiple sibling if blocks in one action are evaluated in order; the first block whose conditions pass runs its payload.

{
  "weight": 10,
  "stages_logic": "DEF_OR",
  "stages": [
    { "stage_type": "player", "stage": "early", "is": true },
    { "stage_type": "player", "stage": "late", "is": true }
  ],
  "do": [{
    "if": [
      [{ "conditions": [0] }, { "drop": "iska_utils:entropy_crystal_early" }],
      [{ "conditions": [1] }, { "drop": "iska_utils:entropy_crystal_late" }]
    ]
  }]
}

• jeimode: hidden + entry not eligible → hidden from grid and excluded from % denominator.
• jeimode: show + several { "drop" } in do[] → one slot with alternating stacks (unchanged).
• Missing mod → entry hidden on client.
• DEF entries stay visible in JEI; % uses the AND/OR eligible pool; DEF entries count in the rollable denominator (documented for pack authors).

When stages_logic and mods_logic are AND or OR only, the whole entry must pass before it enters the roll pool:

{
  "weight": 50,
  "mods": [{ "mod": "artifacts", "is": true }],
  "mods_logic": "AND",
  "stages": [{ "stage_type": "player", "stage": "chapter_2", "is": true }],
  "do": [{ "drop": "artifacts:everlasting_beef" }]
}

• Optional Mimic drop: tag iska_utils:curio_compat/mimic (Dev) — see Home — Configurable Tags. Default tag value is only suspicious_delivery.
• Command items (same message action): Command-Items
