I may sound a bit surly, but have to be honest: it seems you didn't do the proper math on the passive's numbers. 15% of anything is 1/6.(6), so if we were to multiply it by any number greater than 6.666(6), it will result in a percentage greater than 100%. In other words, a single basic attack from Ciemnota will one shot everything since he'll always do more than 26.(6) damage. Reduce the numbers to to be the least bit healthy.

Also, do the Shadows proc any on-hit/spell effects? It's important for balancing purposes.
