Dungeon Master and Chaos Strikes Back Items properties

The table below contains data found in graphics.dat item #559 (offset 7A6h) from Dungeon Master for Atari ST v1.2. Similar or even identical values are found in other versions of Dungeon Master and Chaos Strikes Back.
Some attributes of each item type are described in this table, including their global item index. The table can be used to convert a ‘global item index’ to the ‘item index in its category’ (potion, weapon, etc.).

Here is a description of each column in the table:

• Global item index: Each item type in the game has a unique global item index. This is the index values to use in the data field of some actuators that only apply to a specific item type.
• Item on floor graphics index: this is the index of the graphics to use to display the item when it is on the dungeon floor. This index is added to a base index indicating which graphics.dat item is the first graphics of this category.
  Note: Item on floor graphic #36 is an empty Waterskin but this value and the corresponding graphic are not used:
  In the game, a Waterskin on the floor looks the same whether empty or full:
• Attack combo: This is the number of the attack combo associated with the item. An attack combo is a combination of one to three attacks.
• Carry locations: For each item, a word defines the possible carry locations. Each bit of this word defines a location:
  • Bit 0: Consumable
  • Bit 1: Head
  • Bit 2: Neck
  • Bit 3: Torso
  • Bit 4: Legs
  • Bit 5: Feet
  • Bit 6: Quiver 1
  • Bit 7: Quiver 2
  • Bit 8: Pouch
  • Bit 9: Hands
  • Bit 10: Chest
  • Bit 11-15: Unused
• Here is a schema of the possible carry locations:
  
  An item with word value 0 cannot be carried (apart from the hand mouse cursor, like the Zokathra spell). All items with a non zero value can also be placed in hands and in the backpack. Items that can only be placed in hands and in the backpack must have at least one bit in bit 9 and bit 11-15 set to 1.
• Index in table: This is the index of each item in the present table. To obtain this index, hard coded constants are added to the ‘item index in its category’ values depending on the item type:
  • Scroll: +0 (1 item type)
  • Container: +1 (1 item types)
  • Potion : +2 (21 item types)
  • Weapon : +23 (46 item types)
  • Clothe: +69 (58 item types)
  • Miscelaneous: +127 (53 item types)
• Item index in its category: This is the index of the item in its own category. These values are only unique in a given category.
• Item category: By using an item’s category and its index in this category, you can determine the global item index in the first column of the table.
• Item name
