Guild Wars 2

I just wanted to complete my Verata’s ascended heavy armor, and missed the boots! are they an omission, or what happened here?

The heavy should be "Verata’s Greaves".

I don’t recall getting one of the books to drop, so I cannot confirm or deny if it’s missing from the list when you select which recipe to learn. Is that what’s happening for you? Unfortunate, especially if it’s all you need!
