hunter turns invisible. and walks/creeps. gorgons respond to sound to find you and sight to see and kill you. when invisible a hunter can walk upto a gorgan. In this way the "normal route" can be taken. if a hunter is used to "push" (walk into) the gorgans that are stationary on hard mode. he can push them such they are staring at a rock and not at the group. or run past them and make them turn without being seen. or w/e else they wish to do. this can allow people to get past the maze. though most people know a path and route. still the fact you can turn invisible, run past a gorgan get it to turn and follow the sound you made, and draw it away is useful...particularly if trying to get through unseen but still get all the loot chests
