Can be bought at any point late game.

Depends on the game.

You're a deadly psuedo-sniper assassin that excels at ganks and screwing over one particular enemy every ~45 seconds
Buy all the items in the "Core" categories
Drop your (2) Time Wall, shoot an enemy with your (3) Kinetic Carbine, throw your (4) Paradoxical Swap at them while they're slowed by your carbine, they will fly through your wall, throw your (1) Pulse Grenade at them, then shoot them to death
Good luck!

This build is well rounded early with a focus on dealing bullet damage late game
That said, there are a few options within the build that you can pick to boost your spirit damage
By picking up items like Soul Shredder Bullets, Slowing Hex, Silence Glyph, Phantom Strike, and Mystic Vulnerability you can significantly boost your spirit damage output
Bullet damage focused builds are typically more consistent, but in some games you will see great returns on investing in your spirit damage
If my opinion changes in the future I will update accordingly.

You can use all four of your abilities together to deal a lot of damage
There are many strategies, situational differences, and micro efficiencies that can change the optimal order of the paradoxical wombo combo, so for now we'll keep it simple
Charge your (3) Kinetic Carbine, use your (2) Time Wall, hit an enemy with your (3) Kinetic Carbine, hit the slowed enemy with your (4) Paradoxical Swap, throw your (1) Pulse Grenade at the ground between your target and the direction they want to go (so they have to run through it).

You have three options in this build: Glass Cannon, Phantom Strike, and Diviner's Kevlar
Go Glass Cannon if you are doing well and your team needs you to do lots of damage, Phantom Strike if you're brawling and need better chase or a boost in spirit damage, and Diviner's Kevlar if you need survivability and are transitioning into a more support-y mid to late game role
If you're doing very well, go Glass Cannon
If you're getting into lots of fights and invested into spirit damage already, go Phantom Strike
If you're doing poorly, go Diviner's Kevlar.

Yes!..
mostly
Paradox is great out of the box, but if she's underfarmed late game she'll really feel it
I recommend ganking early, especially once you have Enduring Speed, and then pivot into pushing, ratting, and farming neutrals between roams and ganks
Secure Warp Stone, Superior Stamina, and one big T4 item as early as reasonably possible
By this point you'll have the damage and evasive ability to be an annoyingly slippery assassin that secures your team's late game.

Well, that's the million dollar question
The best tips I can give you are always -- and I mean ALWAYS -- deny enemy orbs whenever its reasonably possible and farm neutral camps often
Seriously, though, deny enemy orbs and farm neutral camps constantly
Punch vending machines every chance you get (the double vending machine room is INSANE)
Also kill heroes
Kill them a lot.

Yes! Stay tuned for more in the future :)
