not sure what you mean...
When you select the item you already see the current equiped effect/gems, and and its stats...do you want to see all the effects combined ? like showing the real effect stats when viewed?
If so, that might be a problem, in order to do that , i need the exact value of each effect...most of the effects have just "+ Strength", or "+%damage"... how would i know what effect gives what?
There is only one way to do this , is to extract the resources from the game data, and use the id's and info from there...witch im working on now.
Currently im trying to extract all the items/effects/images and stuff like that from the game itself, however, the Common.CPK is pretty hard to parse, and may take some time fully parse the data.
Im open for all idea's, so please dont say "Sorry" when you request something.
Il gladly accept any requests, if possible offcource.
