If it were headgears just copy the item_db info of it
Ex.
5132,Angeling_Hat,Angeling Hat,5,20,,700,,2,,0,0xFFFFFFFF,7,2,256,,0,0,[color=#ff0000]204[/color],{ bonus2 bSubRace,RC_DemiHuman,10; },{},{}
The red colored "204" is the view id, to classify which view the item uses. Each headgear uses a view ID.
so if you were to duplicate this Ex.
[color=#00ffff]32767[/color],Angeling_Hat,Angeling Hat,5,20,,700,,2,,[color=#0000ff]1[/color],0xFFFFFFFF,7,2,256,,0,0,[color=#FF0000]204[/color],{ [color=#ee82ee]bonus bAllstats,30;[/color] },{},{}
The Cyan "32767" is a different item ID for another item (must change to a different Item ID not taken to duplicate
The Blue "1" is the changed slot (you can change)
The Red "204" is the same id, so it gets the view id of the Angeling Hat
The Violet "bonus bAllstats,30;" is a different effect (you can change)
Of course you must add the Item description in idnum2desctable.txt
Ex.
32767#
(description)
#
Item Display name in idnum2displaynametable.txt
Ex.
[code] 32767#Angeling_Hat#
And to get the Item.bmp and Collection.bmp You must add the name of the .bmps to the idnum2itemresnametable.txt
Ex.
32767#(name of bmp files)#
