So I read the meta pve build for elementalist, it says I need two assassin rings. How do I get them?

The first link leads to a page that was made poorly on the wiki and is hard to understand.

For ascended stuff tho (which you should want anyways) is straightforward:

For strait answer. You get them both from completing respectively Arah and Cadecus Manor achivement of getting all 37 skins for armors and weapons. Once you completed these achievement you receive the accessories and they are unlocked at the laurel vendor if you would want to buy more, but you can only buy them with Laurels and Glob of Ectoplasm. You can’t buy them with guild commendation like other accessories.
