That's a lot of questions.
Usually it's better if you seperate you question in different posts such that people who search things in the forum can find answers faster
First of all, the UCC + UIS integration is very precise on how you need to use the Invnentory, and if you do not do things precisly as guided you will get errors. Especially the database it must be defined in a certain way.
So make sure to read the documentation for the integration in detail:
The character controller is seamlessly integrated with the Ultimate Inventory System allowing you to use the Ultimate Inventory System inventory rather than the inventory included . . .

In UCC+UIS the "Empty" database that you should duplicate to get started comes with the essential categories and attributes.
You can add an "Attack" as attribute on the item in the editor, but until you tell the UCC Item what to do with the "Attack" value it won't know. To do this you can use Item Bindings (There are other solutions too but that's the simplest one)
The Item Binding component allows you to bind an item attribute to any property of the same type. This means that when the attribute value . . .

For the items showing the amount of items instead of the attack you can use Item Views.

For your last question, this will require a bit of custom code.
You can either make a Attribute of type Material or make a custom enum type with the options of materials as the Attribute type.
Here are some examples on getting attribute values in code:
The Item class is the core of the inventory system. Items are simple objects (not a MonoBehavior or Unity Object) which can be unique or . . .

Once you decide that, you can add a new component on your Character which listens to the event of items being equipped. For example you could use the "c_Inventory_OnAdd_ItemInfo_ItemStack" event to know an Item was added and you could check the itemCollection from the ItemStack to know it was added to your "ArmorEquipped" Item Collection. From there you can get the Material attribute from the Item and swap the Material.
The inventory system uses two types of events. It uses the C# event system as well as the Opsive Event Handler which is used throughout . . .

Another option is to use a custom Item Action. Instead of Equipping the Item by moving it to another ItemCollection you could just change the Material on your Character
Item Actions are used to perform actions on an item from the Inventory. It should not be confused with item object behaviors which are meant . . .

Both options have Pros and Cons.
I know this is a lot to go through but the system is very big with so many ways you can expand on it, so it takes a bit of time to go through everything. I would recommend doing one thing at a time
