im new and i just unlocked it

okay so on dromund kaas
you can go to the legacy vender and buy stuff but you need to be at least lvl 20 legacy for anything decent

my question is
how do you lvl up on legacy
because i looked in the tab and i cant find anything

is there directions on a site that explains this
please lmk
any information is helpful

:] im a noob i know

you lvl your legacy by playing=) You recieve legacy xp just as normal xp....
But legacy lvls are gained really slow compared to normal lvls

I wouldn't worry to much about the Legacy system just yet.. seems to me like there is still alot of things that needs to be fixed and added. I'm also like you I don't know much about it. A buddy of mine said your old space missions add to your legacy lvl even though there grey quests its an easy way to farm legacy exp as well as credits.
