Dwight adrenaline rush

Whenever i use Dwights adrenaline rush against someone who has stun. he is somehow stunned! i thought you cant get stunned when doing your Adrenaline rush? and becuase he is stunned he doesnt hit again.

Multi atks work like that lol their rush functions like a basic atk it means dwight rush is more of a risk reward for example he could get stunned risk could double atk during his at 2 times reward
