Worn Effect on an Item

[trevius]

You can't use every effect as a worn effect. There is quite a limited list for it. There are different spell types and you obviously wouldn't get any reaction from using Complete Heal as a worn effect, and invisibility is the same way. Worn effects are things like Cleave and Improved Dodge and most of the "Improved" ability spells.

Try using GeorgeS Item Editor. It should be a little easier to understand what is wrong.
