I'm posting this because i'm just interested in it.
Yesterday I had the idea to make it possible to upgrade weapons and armors like in several MMOs so they become +1, +2, +3 and so on, which increases the stats.
So I've looked around and found some interesting upgrade scripts. Not really the one of my idea, but nevermind.
So let's take for example the Equipment Upgrade System by Charlie Fleed (

I experienced that this and all the others i found, use new entrys in the database to create the upgraded items. So if I have other scripts which use static item IDs (e.g. Blizzards HP/MP script) it will mess up. The upgraded weapon or armor wouldn't have the additional HP and MP because it's another ID in the database.
So I'm asking me if it's possible to change the stats of individual items with an upgrade system although there are static IDs used in custom scripts without reworking the whole method RMXP is handling items.
Just a few thoughts.
