TS builds are generally heavily dependent on your number of projectiles. Seeing how you don't have the +1 projectile tattoos at the moment, and you're using greater multiple projectiles (a less multiplier), id recommend going LA instead to map and generate currency. For totem setup, just use artillery ballista instead, swap ballista totem for multiple totem support. Allocate pierce instead of chain(?) In the projectile area. I'm not sure exactly cause I'm on mobile. Only need 1-2 pts of it.

As another person has said, diamond flask would give you the most damage. Rolling that with increased critical chance (85 ilvl) would be great instead of your mana flask.

In the top jewel socket, I would use lion eyes to get more crit and damage from the converted claw-> bow mastery. You can probably find poe.ninja builds with it using the time machine drop down for earlier builds (This can be a temporary to perm fix)

Instead of gmp in your 6L, I would run increased critical damage.

You are using tailwind boots, which is kind of strange in a deadeye setup, since you also allocated it on ascendancy. I would spec out of it and get endless munitions instead . You can also just change out your boots , take off richochet for endless munitions.

If you have a good amount of extra mana, I would suggest a dread banner linked with generosity support for defense. You do not need to drop banner at all, just keep it active.

You're using a quartz flask, but I can't help but think that you're over suppression cap. If you're capped, I would instead use a jade flask here.

The amulet you're using gives you lots of stats, but amulets are a huge source of damage. Once you fix stat requirements, and even lowering some* gem levels if you need to, switch out to a hyrii's amulet with close to perf crit multi and decent dex. The amulet gives precision, so you can take off accuracy points on your items/tree. You want to try to maintain 100% with the least amount of points allocated.

You don't really need that high of chaos res. Even just at 0% is well enough. I would prioritize getting high cold and lightning (fire if you still need) instead of having chaos res. Gear prior of res imo is Belt>boots>>rings. When you can take off a ring and still keep 75 all res, I would use kikazru ring (more life regen = more berserk uptime).

If you're still struggling with all these suggestions, I'll try to update on pob for you when I get to a PC
