I think it is a good idea, but I also have an idea of water. If we do in the middle a crystal for everyone who kills her first, he can kill his crystal, for example.
karus killed this crystal in the middle, they can go to the special crystal for human and kill it And vice versa as well, and one more thing. If the crystal in the middle is killed by human after karus is killed it, the damage will stop in the special crystal for human.
