@Jedzkie maybe you can squeeze the update for Type: Item Type in docs/item_db.txt :D

Type:
0 Healing item.
2 Usable item.
3 Etc item
4 Weapon
5 Armor/Garment/Boots/Headgear
6 Card
7 Pet egg
8 Pet equipment
10 Ammo (Arrows/Bullets/etc)
11 Usable with delayed consumption (item is lost from inventory
after selecting a target, for use with skills and pet lures)
18 Another delayed consume that requires user confirmation before
using item.

since Type nowadays uses string rather int.
