- Go here: http://www.entropiawiki.com/Info.aspx?chart=Armor&id=99
- Click Add item
- Set Type as Armor Sets
- Enter tier # (3 in this case)
- Scroll down and hit submit (also click go to item)
That creates the new armor tier entry. I did that already, so you can now go here to enter the rest:
http://www.entropiawiki.com/Info.aspx?chart=Armor&id=99
- Click the tier 3 entry in the table (the number 3 or just armor text)
- Click Add tier ingredient
- Click Add ingredients in bulk and scroll down to find the item again (there are a bunch of dummy tier 0's to go past).
- The items are autofilled so you only need to put in the amounts instead of searching for an entry for each individual ingredient.
I'll leave the later part for you to try out though. It's not intuitive to get it to work, but once you have the roadmap down, it actually goes pretty quick.
