Bouncing attacks and feedback

I want an unit with bounce attack and feedback but the feedback doesn't do anything. What can I do?

I would also like to know if it's possible to get critical strike, bash or orbs work with bounce...

Bouncing attacks with feedback will not bounce if it hits a bounce-vulnerable target.

Same applies to bash, crit strike. IIRC orbs will overwrite bounce. Searing arrows can work with bounce (the searing arrow bounces). Black arrow and other arrow types don't, i think.

Well can you tell me exactly how to make a trigger that feedbacks all enemies hit by that unit... I have this hero with feedback skill and moon glaive skill, they both have 5 levels.
