Assassin/Ninja Help Lvl 101 Build

So, as the title says, I REALLY need a new assassin build. I've been trying to complete LI with some friends over the last couple days with my 101 assassin, and I was using, for some dumb reason, my speed build. Of course, I wasn't getting tokens most of the time, so I tried to switch to poison... That's where I realized that I needed a new build. My poison build deals literally ZERO damage, and I'm getting OBLITERATED (like, 5k dmg per hit or something, I don't understand).
Here's my poison build:
Necrosis
Terra's Mold
Leggings Of Desolation
Scorpio
Arakadicus' Maw
I really don't have much money, but I'll still take any suggestions, see what I can do, but really no mythics. (except if you're willing to donate hehe)
Thank you! :)

 

level up to 103 so you can do EO, then go heavy melee

 

Writhing Growth is overrated imo

(but Gaping Cavity is nice)

 

if you wanna keep a poison build you can try something like
https://wynndata.tk/s/tc9syg pretty tanky but dps isn't too great (vanish might help, but idk if it affects poison e). you can also try forest aconite

here's a higher dps thing (rodoroc's guard!)
https://wynndata.tk/s/6maz1c you can use scorpio if you are willing to throw away your water def. you'll need to replace a saundersi with impudent tho
