Skills do have an achievement tied to them. If you are able to collect each and every elite skill from a campaign, you will be able to have a dedicate-able title for each campaign towards your Hall of Monuments, plus an additional one if you collect all of them. However, this costs a little: about 1,000 gold per Signet of Capture and there are 350 Elite skills between Tyria, Cantha and Elona towards the title track and you need to acquire 290 of them (no Eye of the North elite skills count towards this). That means you need to have 290,000 gold (or 290 platinum) in order to get these titles.
