SoJ Assassin

I was looking at all deadly art assassin builds that are posted and that exist.
I know that deadly art needs improvement,and maybe I found something original and that works.
I got idea when I was playing my monk smiter.His 1 smiting skill made this build:

Deadly Arts:15 ( +3,+1)
Dagger Mastery:13(+2)
Shadow Arts:8
Smiting: 3 XD ( you don't really need any points in it)

Build:

Signet Of Judgment
Falling Spider
Blinding Powder
Death Blossom
Impale
Signet of Toxic Shock
Signet of Shadows
Optional ( Shadow refuge,Res,Iron Palm)

This build is for PvP. Your optional skill makes this build different.
example:
for AB (when you have a monk in team): you use Iron Palm
for AB (when you don't have monk): use Shadow Refuge
For TA,RA or some other arenas: use Res

you don't really need Iron Palm,but it make you have 2 combos,not only 1
Example:
Your target is hexed or have condition,cast Iron Palm so it can save your SoJ for later

Weapon: dagger with +30 hp and +5 energy mode
Armor: whatever(i think)
Runes: rune of sup vigor (+50hp)

This is what I made.I need your comments and maybe improvements for this build.
I hope you like this one

Did you tried build?
Please post some critics or comments and maybe some improvemets

Might as well take Shove, it's just a bit faster, and you'll be 100% sure of being close enough to your target when you're going to use FS right after it
