Soul of Wisdom

I’ve read this about the Soul of Wisdom - "Soul with special powers. Has a high Bp requirement. When Sacrificed it gives off a lot of life force." - Can anyone confirm this?

Yes, that is indeed correct. Depending on the grade that you get, all of the base stats aside from bp is going to be 1 while having a B will result in a bp of 100 while having a B+ will result in having a bp of 150

I know about it's stats but what is it actually for?

My best guess given the description I said earlier is if you power up a monster using the Soul of Wisdom it will give the same about of exp as 5 monsters (just my 2 cents)

Well, I'd guess it gives off BP equal to its BP. Next in line are EP and exp. Try it and see!

Or give it to me and I'll try it
