It sounds like you want to create a new category. Categories let you "group" a bunch of related pages (eg. a group of item pages), and have them show up with their own page. For instance, I made a category for all items that give Invisibility:
https://wiki.project1999.com/Categor...sibility_Items
To create a category, you just have to add [[Category: Your Category Name]] to the bottom of every item page that's in that category. For instance, if you
edit the Cloudy Potion page, you will see that it has several categories at the bottom:
Code:
[[Category:Inventory Items]]
[[Category:Vendor Sold]]
[[Category:Invisibility Items]]
Of course, making a category with every item with a worn effect will be a lot of work ... you might want to try making a smaller category (eg. "Underwater Breathing Items") first.
