Modify item properties (Ex.:Damage)

[Abextadoo]

I want to modify an item property permanentely, but there is no such option on object editor. How do i do it?
Example: I want to make a custom item claw of atack based that adds +60 damage.

There are Items and there are Abiltiies.

If you want a Claw of Attack with a +60Dmg ability. You have to create the +60 Dmg ability and then add it to the Claw Of Attack Item. (The first data field of Items are the abilities it's composed of)
