Terrible idea to bring science to a magic fight. So, the grenade isn't going to hurt anyone but the crowd you tossed it into. I'm not sure what you planned on accomplishing throwing explosives in a crowded bar, but I can assure you it isn't going to be a simple 'hit guy and done'. That shadow is now going to be trying to stab you, and unless you dropped that grenade at your feet its not going to stop it. 

The Nightshade is around adept level, which is why the shadow is able to beat on you without the controller having to stare at it the whole time to make it move and strike. While they do have varying degrees of how far along they are (Mage-Adept is generally where they are.)
