! Record !! Col / offset !! Meaning !! Evidence
|-
| Item (all types) || col7 = <code>0x3c</code> || buy price || <code>State_NpcShopBuy_Tick @ 00467fd0</code>: buy allowed only if <code>record-&gt;0x3c &lt;= player.money</code>, then sends <code>0x35</code>. Ring col7=100000, weapon 9000, matches.
|-
| Item || col8 = <code>0x40</code> || sell price (inferred) || Not consumer-confirmed, but the buy/sell pair — ring col8=5000 vs buy 100000; weapon col8=900 vs buy 9000.
|-
| NPC/shop (type 0xB/0xC) || col7 = <code>0x3c</code> || shop-type code || <code>State_NpcShopBuy_Tick</code> case 0 switches on <code>npcRecord-&gt;0x3c</code>, accepts <code>0x44,0x47,0x4a,0x4d,0x50,0x53</code> = letters D G J M P S (shop kinds).
|-
| NPC/shop || cols 9–22 = <code>0x44</code>–<code>0x51</code> (14 bytes) || per-category "sells this" flags || same function loops <code>npcRecord[i + 0x44]</code>, <code>i = 0..13</code>; each nonzero byte adds item-category <code>i</code> to the shop's list (14 categories: Katana…MonsterItem).
|-
| Item / emblem || col6 = <code>0x38</code> || class/icon bitmap index || <code>cpt_panel_status_widget_Draw</code>: for the party-leader emblem (dat 9), <code>record-&gt;0x38</code> is passed to <code>File_Read_Bitmap_Archive</code> as the icon image id.

'''Server relevance:''' col7 (buy price) is the value the shop's gold check uses; an equipped item's col9–14 bonuses (OFC/DEF/AGL/LUCK/LIFE/FOOD) are applied to the wearer's totals. The player's ''total'' stats (base + all equipped bonuses) are computed server-side and pushed via packets <code>0xC001</code>/<code>0xC002</code> — the client never re-derives totals from records.
