I dont know if im using the right auras and and i feel like my survial ability isn't the best either idk where to go from here other than put more skills into attack speed,critical, and poison

You have no life, next to no energy shield, only 2 labs done, picked Kraityn as a bandit, not capped resists, bad flasks, having only a 4-link and playing poison build on Trickster instead of Assassin. I don't think this build can go far because it bears all the problems of homebrew first time builds.

Cobra lash is not a very popular skill this league, but it's still playable if you optimize for it. I'd suggest check a guide what to aim for, one of them is: https://www.youtube.com/watch?v=ef8kaq5ynqY but you can probably google and find something else too.

Otherwise I'd highly suggest picking up to date build with good guide coverage and playing that instead, the efficiency difference will be very big, you won't have to wonder whether you did something wrong or is it the skill / class and you can always ask in guides for extra advice and tips.
