I made this build for my StJ/Nin stalker and would like to get some advice on it.
I am new to making builds so there are probably gonna be many noob mistakes.
I tried to make this build fairly cheap because i don´t have that much money to use, but i am planning to slot it with PvP IO´s and purples once i have the money for it.

Thanks.

I am new to PvP and decided to start with a stalker. I took SJ/Nin because my friend recommended it. I would like to know what should i build this character for? I would also like to know are there some strategies that i could use.
I am willing to spend 2 bill for his build.

Thanks.
