Tu’rani’s Bident is not good enough in my experience. It’s nice to partly level with but that’s it. A good rare/exalted Deicide Lance will work better. This is the build I theorycrafted: Paladin, Level 100 (LE Beta 0.8.4e) - Last Epoch Build Planner. Some basics that you need to change in your build for sure are: increased health on chest suffix, no increased elemental dot on belt prefix since it’s useless for you, at least 1 more smite on hit idol, I think you could do with less throwing attack speed (see rings), get to 60% endurance, and those last 2 blessings. You need to overhaul your passives since you should take 10/10 abyssal endurance and, if you are struggling with mana if you change your build, 10/10 dedication. For skills: do not take Faith for Sigils of Hope, follow how I spent the points for Smite and Lunge, and change your Javelin points. For Javelin, you take 1/4 in Beast Ender but you are trying to crit as much as possible (seeing some of your prefixes) so invest fully in it. I would also change other things but that’s up to you.
