Assassin/Ninja lv 50-60 Acrobat build?

Trying to look for a build that both gives me damage and prevent me from dying too quickly (I die quite often). I plan on going for a morph build but I'm not sure if that's a good idea for now

below is my current build:
https://wynnbuilder.github.io/build...07300A0CM0S0U0U0P0P0r000010007l0z0z0+0+0+0+0-
WynnBuilder build:
> Avalanche
> Narima Pasukan
> Morph-Iron
> Morph-Gold
> Morph-Emerald
> Morph-Topaz
> Buster Bracer
> Durum's Serenity
> Hashr Claw [w3w3]

any help is appreciated :D

 

Personally i'd run a shadestepper tree+ this build
Acro isn't that good until later
