Assassin/Ninja Need some help with my shadestepper build

Hi, I recently joined back onto the new spellbound update, and I found that the survivability of my tierstacking build is super low, so low that I can't solo qira hive XX, so please leave any alternate suggestions on how I could modify this build to make it better. Thank you!
My build:
Ambertoise shell
Soafae
Second wind
Nether's Scar
Flameshot hilt
Breezehands
Flashfire set
Altium spatium
(Shadestepper/Trickster) hybrid

 

melee assassin isnt as good as it used to be, tho heavy melee is still kinda usable
i would suggest this build for flameshot now, focused in backstabing enemies
