Hi, been playing kuno since started playing and few tips and tricks i want to share.

1. best in my opinion addon i'm using currently at lvl 59 is THIS.

will probably get Lunar Dash with evasion and attack speed at lvl 60.

2.Abosuletly must get first maxed! in that order.
Tendon Cutter whenever possible
Shadow Stomp
Fatal Blow with both flows!
Smoke Screen & Heart Aiming
Ninjutsu Shadow Clone
Ninjutsu Black Moonlight
Suicide Fall
Floor sweeping(get absolute only when u can afford wasting sp)
MY OPINION BEST LOCKED SKILLS ARE
Ninja evasion
Crescent Slash
Fox Claw
Shadow Explosion
Flash Slash

For awakening you should get everything whenever possible
!EXCEPT THOSE! DO NOT LEVEL THEM!
Sah Spree of Sonan
Flow:Block Jump
Flow:Indignation

Rabams
Sinew Cut and heart snatch (haven't tried assasin's trail but i think they are both equally good)

3.Few Skill combos you should use in pvp.
a.Shift+Q-W[orA&D]-E (Block jump-Cursor on target-teleport grab) (any stance)
b.S+F into tendon cutter does more damage than S+F S+RMB but both viable options. (awakened)
c.RMB-S+E-[180 turn]-space (animation cancel shadow stomp + shadow clone) (pre-awaken)
d.AorD+LMB-Shift+LMB (cancels first skill animation)
e.whenever you use tendon cutter you can and should move your screen to position yourself closer or further from target and be less predictable
e.Full skill combo 100 to 0. my favorite.
Shift+Q - W - E - LMB+RMB - black moonlight - Shift+RMB - AorD+LMB - Shift+LMB - S+F - 90 degree turn tendon cutter - RMB - S+E - 180 degree turn+space
