BM Questions

[Eres]

As the title says i play Blademaster.

 

What do i have to do or what is the counterplay when:

 

-A destroyer grabs me (i guess i have to use 2 but i dont know when and it seems like it never does anything)

-A LBM has the mode where he is resistant to damage and status effects

-An assassin is invisible

-An assassin has thrown his dagger on me and it is in my back

-An assassin uses Shadowless Step on me (I get caught by that everytime i just dont know how to prevent it)

 

Thanks for answers
