The rebels should be able to teach you how to shape spawners. There should be many diferent levels of spawners that shape diferent creations. All of the creations shaped by them should be weaker than the ones you can shape normally and shoud not be able to be controlled at all and the spawner should have a tendancy to go cazy and turn on you that goes down the higher your level at shaping them is. They should be fixed in position and you should be able to have only one out at a time. The spawners should also be able to have about 5 living creations at a time and the spawner should have lmited essence but there should be spells to restore their essence. The spawners should also have only a small amount of health and they should die when you leave the area. Jeff shold feel free to change my idea n any way if he uses it. I hope you all like my idea.
