ItemAdd.ini file

If you delete all the information in this file, and you go into the game and you have example:

PhoenixHat (+3)
DEF: 100
MDEF: 100%

but no stats under it, what you normally see in purple like:
+34 DEF

cant we change this? or is this also server sided(problally)

its serversided...thats why you only have to log out when you add another + to something, as opposed to having to close the whole client. Nice effort though :)

The ItemAdd file is simply used to siaply composed amounts, because the only information in an Item packet it the amount its composed by (+3 for example).
You can edit the ItemAdd file so it shows different amounts on the display, but the only use you'll get out of that is making screenshots to show off.
The itemAdd file has this structure.

[ItemID] [Composed Amount] [+HP] [+MinPh-Damage] [+MaxPh-Damage] [+Ph-def] [+Mag-Atk] [+Mag Def] [+Accuracy] [+Dodge]

Each + can be a number between 0 and 65535

the item ID is based of the IDs found in ItemType.dat

OH! Youve really figured it out thanks for the info!
