Guild Wars 2

I’m leveling a new character. And joined the priory. At level 70, I wanted to look at the armor and saw “Priory Equipment Guide”.
https://wiki.guildwars2.com/wiki/Priory_Equipment_Guide

This sounds like it unlocks all the skins for all armor and weapons. But I bought it – at level 70 – and used it. It looked like it succeeded, but nothing. And no other toon sees it on the merchant now.

So, what does this do? I don’t have any of the skins at this point.
Bugged because I used it at level 70 when it says level 80?
Or do I have to log out and back in for it to work – another bug?
Or do I completely misunderstand what the heck this is for?
Thanks a ton,

So I gather that the Guide unlocks the “Collection Achievement” not the skins for the weapons and armor. So I gather that to get the Achievement, you first have to get the Guide and in addition all the skins too. The wiki and the item description are not clear. Adding the word “Achievement” to the descriptions would clarify this.

People answered you in detail in your other thread with the exact same text, which is why I deleted my first response in this one. It was redundant.
