lvl up bicheon first b/c you are pure strength. then lvl up fire for imbue, phys attack increase, mag defense, and fire shield series. lvl up ice for defense (i lvled up the nuke b/c i like dropping ice on ppl, but its only to kill noobs). lvl up light for mag attack increase, parry ration increase, and speed is much needed for bladers. i lvled up pacheon to 10 for the attack rating increase too but that is just for a little extra

your build is up to you, this is my choice but there are thousands of ppl out there who feel otherwise. just be patient because bladers lvl SLOW. farming at lvl 16 is a great idea and will save you some time later down the road, you will still probably need to farm in the 50's though. good luck
