Archer/Hunter Is this good enough for endgame fights?

Man, those Frumans pack a punch, I am afraid my current build isn't good enough to survive lvl 117+ boss fights and War Torn Palace. Please tell me how many DPS and EHP I need as a no-mythic sharpshooter to comfortably survive endgame fights.

And I tried to tinker with my current build to make it more tanky, please rate: Archer 117 - general

 

I personally use a Twain’s Arc-based gimmick build (EWF but mainly fire damage), might not be your style but it gets the job done
-Recursion
-Titanomachia
-Abiogenesis
-Doomsday Omen
-Gaea-Hewn Boots
-Fireball (going to replace eventually)
-Downfall
-Dupliblaze
-Dogun Sautoir
(fire powder on everything)

I don’t remember what my ability tree is, but I will share it tomorrow, same with skill points

 

I assume this is the build, looks pretty good. Although I am not familliar with Twain's arc build.

 

It’s basically just melee-focused sharpshooter, not really using crep ray (also I don’t think it’s an actual term people use I don’t know what else to call it)
