You can go in two ways :
--> semi-expensive build but it takes time
Just pick 5LUC 2 DEX and link many low level +STR lapis (mainly - like lvl3/4 craft) and fill with DEX on your gear until lvl30. You can lvl up without linking but believe me, it's darn so slow without having +STR and +att lapis (like assaults for your bow). Leveling from 1 to 15 shouldn't be hard but it will when you want to level up from 16 to 35.
Once you have reached lvl35, the LUC build will start to be efficient. You can also get a complete dread set ( AoL dread quest guide
) which grants you enough slots to link lapis with. Use mainly +STR lapis ( lvl3/4/duals ), followed by +DEX and then by +LUC. Ofc you can lvl up without linking but i still recommend to do that. If you link your gear, you are stronger, which will fasten your grinding process.
At lvl50, go for a 3 stat build : STR/DEX/LUC (see bottom) and invest in 5STR 2DEX
--> expensive build but it takes less time
Start from 5STR 2 DEX and once gotten lvl30, you can consider for a restat by using a restat stone. Restat to 2DEX 5 LUC per level build and fill your gear up with lapis like here above. Or keep this build and link only LUC. Try to aim for about 475 LUC, although it is an expensive way. Once gotten lvl50, go for a 3stat build.
At lvl50 : 3 stat build
This is a strength for the archer class : a nice and solid 3stat build. this build is only possible if you can afford gear which can bring up at least 1000 stats in total. Link your gear first with at least lvl5's and fill the remaining slots with either some lvl6's or duals. Once done with linking, use your leveling stats ( use restat stone ) to invest your stat points till you can achive your goal : 200+STR 300DEX 500LUC. If you can add more stats, feel free to focus on STR, which is important. But don't forget DEX. At lvl70, 350 DEX is a minimum, but i'm sure that you have other gear at that point, so 300DEX should be enough until lvl65.
Please note that this class is one of the expensive class in this game. As you can see, you need a good gear, or your class won't effective.
