Unique Item Data

Unique Item Data

Beginning offset in Diablo is 7CCB8 (7BC68). In Hellfire, it's 8CB00.

Each unique item is 84 bytes in lngth, which is a little more than 5 lines in a hex editor. Place your cursor at the starting point of a unique item and drag it along until you see this at the very bottom..."Sel 0x54". Everything you have highlighted is the data for one unique item.

**Note** As with the prefix and suffixes, the first byte in each data string will be byte 0, not byte 1.

Bytes	Effect
0-3	Pointer to name As with the prefix and suffixes, the way to handle the pointers are the same.
4	Item type These can be changed to whatever you like. Say you don't want the Dagger to be used for a unique item, you find the Dagger in the base item list and null out the item type value (00) and give 07 to whatever base type you wish (ie, Gothic Plate). Now, find the unique daggers (Gonnagal's Dirk and Black Razor), and create your own plate uniques. :-) Defaulted to the original Diablo values 01 = Short Bow 02 = Long Bow 03 = Hunter Bow 04 = Composite Bow 05 = Long War Bow 06 = Long Battle Bow 07 = Dagger 08 = Falchion 09 = Claymore 0A = Broad Sword 0B = Sabre 0C = Scimitar 0D = Long Sword 0E = Bastard Sword 0F = Two Handed Sword 10 = Great Sword 11 = Cleaver 12 = Large Axe 13 = Broad Axe 14 = Small Axe 15 = Battle Axe 16 = Great Axe 17 = Mace 18 = Morning Star 19 = Club , Spiked Club 1A = Maul 1B = War Hammer 1C = Flail 1D = Long Staff 1E = Short Staff 1F = Composite Staff 20 = Quarter Staff 21 = War Staff 22 = Skull Cap 23 = Helm 24 = Great Helm 25 = Crown 26 = *CRASH!!!* 27 = Rags 28 = Studded Leather Armor 29 = Cloak 2A = Robe 2B = Chain Mail 2C = Leather Armor 2D = Breast Plate 2E = Cape 2F = Plate Mail 30 = Full Plate Mail 31 = Buckler 32 = Small Shield 33 = Large Shield 34 = Kite Shield 35 = Tower Shield , Gothic Shield 36 = Ring 37 = some phucked up scroll 38 = Amulet 39 = Undead Crown 3A = Empyrean Band 3B = Optic Amulet 3C = Ring of Truth 3D = Harlequin Crest 3E = Map of the Stars 3F = Golden Elixir 40 = Arkaine's Valor 41 = Veil of Steel 42 = Griswold's Edge 43 = Lightforge 44 = Staff of Lazarus One small note....the item type here is the exact same as the item type for the base items. Some base items, such as the Short Sword, do not have a value here. If you give it one, either an already used one or a number that does not appear here, like "45", you can make a unique item with the item type "45" and you can have a short sword unique. Defaulted in Diablo, the Club/Spiked Club and Tower Shield/Gothic Shield share the same item type value, which is why the Gnarled Root and Stormshield can appear on 2 different item types.
