As said too strong, if you want to keep the damage he should have steep costs. Suggestion: change it to energy, passive energy per 5 decrease by 75 when moving while stealthed, becomes -25.

Q change true damage to 30/50/70/90/110 in addition to Physical damage. Cost 80 energy

AS too absurd, change to 10/13/16/19/22, remove damage reduction. Cost 30 energy

E increase base, reduce ratio cost 80 energy. Maybe change CD to 8 all levels. 100/120/140/160/180 + 1.2 Bonus AD,  120/150/180/210/240 + 1.6 Bonus AD
