Hello I'm currently considering creating a new assassin and I want her to be a hybrid assassin martial arts/traps and down the line a WW/trap sin.
I have almost no experience with assassins and don't really know how I should skill/gear her. Any help here? Which martial arts/trap abilities should I use? Thanks

Just letting you now, WW is awful in PvM.

Kick/Trap is pretty good.

20 LS
20 DS
20 SW
20 CBS
Enough for 24 or 30 Dragon Talon (5 or 6 kicks)
1 BoS
1 Fade
1 CoS
1 Mindblast

You could also get Shadow master instead of another trap synergy, but I always find it annoying.

Gear:
Weapon: Stormlash / Cta
Shield : Stormshield / Spirit (Lay traps on switch)
Armor : Enigma
Helm: +2/20 fcr Cham
Amulet: Maras or Atmas
Gloves: 2 MA 20 ias / Dracs if no atmas
Belt: Arach
Rings: SoJ / SoJ (Ravenfrost if no Cham)
Boots: Double upped Goblin toes or upped Gores

You can have a look at my kick trapsin walk with Stormlash.

I am currently playing trap/kick with the goal to do as much of the gearing myself and try something new I calculated myself and hopefully learn a lesson while having fun.

The build i am aiming for:
2/20 circ ChamShael
2/10 adds amulet
2 assa fools claw BerBer (nothing too expensive)
5ls 2x7fhr&res jool
Fcr rings with ar mana adds
Enigma
Arach
Gores
Dracs

Some Trap charms
