How to get the last point of a skill?

[GreenBunionSoup]

I'm new to the game, like a lot of people. I only started playing about a month before release during the beta. I've wondered since hitting level 15, but what are those achievements needed for the last point in skills? I'm a level 23 Kung-fu Master and want to level up my Tiger Strike to max, but I need to get the "Swift Strike Mastery". Then I check for the last point of Counter and I need the Fateful Tome- Counter, and has the achievement logo. Where do I go to find out what I need to do for these?

I would like to know that too...

Those are "legendary" skills that you unlock through end game dungeons, pvp, or achievements. They are not obtainable yet.
