Hello , if i understood well , you are new to the game so i'll advice you as a starting build a Glavier since its very easy to manipulate , very strong and really fun . I advise you to take Heuksal Fire Light because in the beginning you'll need to have some fun ( 90% chances you will not continue in the same char so better have fun and learn about the game for now)
With light you have speed (For free

D) , and ghost walk phantom which are very fun and pleasant , heuksal fire/cold is a hardcore char only good when you are pvping strong poeple and its not really fun when you don't know that much about the game , when you get some experience then go for the Heuksal fire/cold because its stronger and better in pvp.
Edit : and of course its gonna be Full STR all the way
