You need 50% dmg reduction and enough attack rsting to be able to hit stuff. AR is a big problem with WW sins. Shadow GCs contribute much more to fade (DR), claw mastery (dmg and ar), mind blast etc.
You have to decide then whether your emphasis is more on traps or WW. If it is traps, you need 102 fcr, +2 amu (no highlords), shadow dancers and open wounds from fury. You damage with venom and open wounds only while running away from melee, that's your game then, the main dmg sources are traps and mind blast.
Hybsin version where WW is the focus was nerfed with patch 2.4.3, not really recommended. The you have a pure ghostsin with emphasis on WW. There, you can go full rambo with shadow gcs, 3/20/20 , venom prebuffs etc. Mind blast is a real dmg source. You go with 65fcr, highlords and gores.

A hybrid won’t get 50% DR in 102, unless they are using cube buff claws. A hybrid should only be putting 1 point into fade.

it’s important to make a decision on if you are a hybrid, which has traps that deal damage, or a ghost, which just has lvl 1 traps for stun.

Ghost is all about your WW damage
Hybrid is a mixture. But in d2r, a hybrid is more focused on WW damage. In d2 legacy, a hybrid would be more focused on traps. Only when a hybrid has a 2sin/3ls/fools/Eth rep/250+ Ed claw on legacy do you start to try to scale WW damage.

Genebralt spwaking, both a ghost and hybrid is going to use 9x shadow disc GCs, or 8x with cube in inventory for cube buff. Depending on your claws and the + skills on them, you can potentially get away with 6-7x shadow GCs and 2-3 trap GCs. But again, this is dependent on you having a chaos with the correct skills and your other claw having the correct skills. And even then, particularly on d2r, the focus should be more on WW, which means shadow disc GCs have priority over trap.
You made mention somewhere that you are using a COA. No sin should ever use coa.

Are ghosts viable for pvm? I wanna do something other than traps

Would be viable to farm P8 with a ghost or hybrid sin?
Or they are exclusive pvp?

No



You will spend tons of time in town repairing your chaos. Nor will you be able to maintain enough gold to keep it repaired.


WW sin is not viable for pvm because of this. Not to mention assassin WW is low damage so it has bad clear speed.

Cube:
6fade claw/2facer x 2 (6/6/2 ofc would be better)
Demon limb
Mara
Soj or bk
Soj or bk

No shield beside cta to avoid the need to drop items while cube casting.

=
+2 levels higher bo than without cube
+9 levels higher fade and venom and +20% psn(helps once)
+218% bonus to attackrating
-65 life/1 to skilltree/possible 3max-20ar or 5@

Beats any other inventory item...

Dno if any1 tested it yet or done the math, but one could actually probarly reach around 6k bladeshield damage instead of traps, and same damage on blade sentinel and 10k on blade fury as a hybridisation instead of light traps.

6k added physical dps to all in range is pretty decent buffed melee add.
