Blast Rain Deadeye Trapper

Hi guys!

I've recently been playing a deadeye blast rain trapper in SSF kalandra, and it did surprisingly well. I've decided to migrate it over to trade league so I can mess around with equipment a bit more and figure out the build. This is the current pob:https://pastebin.com/9FHyPkJy

It's level 87 and counting all projectiles sitting on 1.1mil dps per trap.

I'm looking for advice on making the build tankier and although the sheet dps seems good it doesn't really 'feel' good against some rares and bosses, and I would love to find a way to not have to run an enduring mana flask. I know I can use slavedrivers (and I can afford them) but I'd like to see if anyone has any other ideas on how to solve this.

The plan is to take the remaining jewel nodes and survivalist as far as the tree goes. It's been a while since I've created a build from scratch so just hoping to get some criticism and input on how to improve it (I'm pretty sure I've missed some obvious ways to improve the build).

For example I would love to run grace + determination but I need precision and clarity too. If I run a conq efficiency and pick up precision costs 0% and drop defiance I can do it, but my unreserved mana pool will be pretty small.

Any input much appreciated!
