people always ask where can I find strength sphere's or where can magic sphere's be found at.....so I got bored and made a sphere chart.....
you can get all the sphere's you need(strength, magic, hp, etc.) from the battle areana species conquests..... here goes
name sphere type #
fenrir agility 2
pteryx evasion 2
hornet accuracy 2
vidatu MP 1
one-eye* magic def 2
jumbo flan magic 1
tanket defense 2
juggernaut strength 1
ironclad HP 1
*note on the one-eye I get 2 dark matter every 4 fights. and also amounts on each can vary I've gotten as many as 4 magic def spheres at one time. hope this helps out a little :-).
