Need build tips for deadeye endgame

Hey fellow deadyes or other OG exilers who has more knowledge than me. I want to improve my build but dont really know how. Items are getting very expensive for small upgrades. I feel powerfull but im getting one shot alot. I have been looking at some uniques such as against the darkness and the unique life flask but i really dont know where to get the most bang for my buck. I have about 50 divs to spend currently. All help is appreciatet.

You need Energy Shield. Wind Dancer is also a must imo. Ghost dance too, if you have the spirit/slot.
Replace pure evasion body Armour with evasion energy shield. Also olroths life flask (put lifetap gem on volt skill then after volt use life flask to put up health buffer)
Your build looks extremely similar to mine. Full evasion build which is extremely unpopular. My lightning arrow does 137k dps unbuffed in the skills tab, POB says 190k which isnt entirely accurate because POB does not account for "Inspiring Ally" which applies companion damage to your damage. Getting one shot can be inevitable sometimes. To really lessen it you would have to completely change your build to have energy shield, New tree and new gear. I just play more carefully and i do okay, but sometimes i do die. Maybe next league ill try an energy shield build. As for increasing your damage, your biggest boost will be getting a new bow. Overall its good, but something with more increased physical damage and more crit hit chance will help alot. My bow is 570 dps overall, and i think the increased physical damage modifier is 230%. Secondly, getting +2 Projectile Skills on your quiver, and +3 Projectile Skills on your amulet also helps alot. Unfortunately with it being so far into the league, and the current status of the league, prices are severely inflated and getting good gear for a good price is very difficult
Edit: Getting a heavy belt with an additional +xxx Stun threshold modifier can help alot also if you're getting knocked off your rhoa. Mine is 24% + 300ish
My deadeye did the lightning spear TT popped a HH on it and it zoomed maps. Bossing was a bit rougher as the HH doesn't help that unless you're able to go in with stacked buffs.
I think the HH was 30d when I got it not sure if it's still within your budget. But if all you wanna do is smash maps quickly not much can beat it.
