The creature barely got even the chance to get to its feet and try and make a cry before the eldritch bolt slams into it knocking the wind out of it and inflicting horrible necrotic pain on top of the eldritch energy surging through his body. However the arrow that drives itself through the heart and the head of the beast managed to make it fly backwards back into the mud with a sickening "thwack" from the shafts finding their mark. It lies still and unmoving before the rest of the party could register what had just happened. Whatever that thing had tried to do died with it. They probably could have guessed it's intentions if there was but one of them.
