Help Repairing Items?

I just got into playing again, and item durability is a new concept I haven’t learned about, I tried repairing an item that I got from the identifier and it wouldn’t work, I have the scraps, how can I repair items that I haven’t crafted

 

Only crafted items (and gathering tools) have durability. Normal items do not need to be repaired. You repair durability simply by going to a Blacksmith, go to repair items and click on the items you want to repair, as long as you have enough scrap.

 

Then what is the percentage next to the wands and armor names?

 

They show how good an item is based on its ID-s. Eg. an item has the ID Spell Dmg % going from 5 to 10%. If you have an absolute value of 8%, then that results in a relative value of 60%, shown next to the ID. This relative value is calculated for every ID, then averaged. This average is shown next to the items' names. This is a Wynntils feature amd doesn't exist in the vanilla version.
