Q about wild machina and bevelle

im just wondering how you figure out who made the machina go wild? And how to get crimson sphere number 1. Im in chapter 3 again (new game plus) and it wont let me into bevelle. Should i go kill ixion and ifrit or whoever is at besaid?

please, can anyone help?

in chapter 4 you can use the commspheres to do the machinas gone wild mystery. And now you are in chapter three you should go to besaid and kill valefor and in killika ifrit. After that unless im messing one you should have to fight ixion in djose temple. as for crimson spheres i can’t remember but i think it is available in mushroom rock road. The den Of Woe.

Crimson Spheres in Chpt 3:

Bevelle:the place you fought Bahamut(only after Djose becomes a hotspot)
Chateau in Guadosalam:Secret area in a chest

im pretty sure therem are more but i cant remember off the top of my and while im hungover
