Archer/Hunter End game build help/suggestion (mythic/no budget)

Hello, this is my first playthrough and I am looking for some endgame build advise. I prefer playing Spell Spam Sharpshooter and would like to make a mythic build. Currently I am thinking of getting the Spring

I would like good sustain damage (200k+ if possible) with some survivability. Dont wanna be a total glass cannon.

For skill rotation:
FireBomb[x2] -> normal hit -> phantom ray
[if there is better rotation please do let me know]


My current gear is this. Iam lvl92 atm


WynnBuilder build:
> Sequencer
> Seagazer
> Dark Shroud
> Ensa's Ideals
> Photon
> Detective's Ring
> Dragon's Eye Bracelet
> Tenuto
> Torrential Tide [w6]

 

Tweaked a build (image below) to have Fire Creeper + Scorched Earth at your request:

WynnBuilder build:
> Aphotic
> Conduit of Spirit
> Efteling
> Moontower
> Diamond Hydro Ring
> Diamond Hydro Ring
> Breakthrough
> Contrast
> Spring [w6w6w6]

Should sustain Phantom Ray - Bomb - Bomb repeat, even if there's a little drain
