That's right, pick between these 2 awesome powers
All-sight:
You gain perfect vision, AND , you can also see at the microscopic level and as far as heimdall. in fact, any power in all of fiction that has to do with eyesight is granted to you and at your complete control. from x-ray vision to ameterasu. you also get ultimate insight, if you gaze your eyes on something you completely understand how something works or how it is made.
All-voice:
You gain perfect pitch, AND every power that is related to speaking and hearing. this also includes powers unlocked by songs and normal speaking (from casting spells to chants that unlock power, even if said power usually needs more then just the chant) also at your complete control.
I'm sure both powers damn well give you omnipotence, but which do you prefer?
