Getting Mastery Points in Tyria
central Tyria mastery points are gained by doing achievements. this wiki page lists what they all are:

or you can look at your achievement panel in game and see which have a red coloured mastery icon.
hope that helps some

A word of caution though: each race’s early personal story chapter shows as a mastery point, but what the wiki is (poorly) trying to show is that any one of those chapters awards a point only once.
So if you do a chapter on a human, you get a point.
If you do that same chapter number on a charr, no point, you’ve already been awarded it.
So if you’ve completed your personal story, no points there for you. You do get the achievement points and whatever other rewards completing the chapter gives, though.
