Ah, this time I made nine spike balls. I use two cubes. The first one is for the needle, while the other is for ball. Then, combined to be a spike ball. Then, I duplicate the spike ball into nine spike balls. After that, I add the RayMirror effect at value of 0.75 which reflects a lot. Then, I made the room again.
Ah, the nine spike balls. I hope the needle is sharp enough, not like before XD. Now, I will try to combine one of them with my previous weapon next time.
