I guess with this we can upgrade any gear indifinitly.

- Yes, you can update and create new traits as you like. No limit :)

Is there a way with any of your plugins to also change a gear's description and and name so that the trait change is supported with flavor? 

- Hmm... there is not. But that is a nice plugin idea. Custom names and descriptions for items and equipments. Will add to my list to do it :)

I mean, you can change that on runtime, but the change will not persist with the save file. For example:

• $dataWeapons[3].description = "New description here"
• $dataWeapons[3].name = "new name here"

If you have a way to always load a common event when the game starts or load a save file, then you could restore the descriptions and names of the dataObjects by using variables. That can be a lot of work, but if you are willing to...

Otherwise, you can wait that I will make a plugin that you can change that.
