What to improve on my slayer? Dual Sword impale Cyclone

I already did all maps up to 15, vaal temple, atziri, uber atziri (deathless).

My @res are arround 80 in ho, mana is fine because i dont use it, dmg is huge arround 1mil dps shaper.

But my life is 4600. I am feeling like 1shot. What would help me? Maybe steel ring with assassins mark? Enchant at helmet? Or maybe gems? HELPH
