How can I remove Beast Instinct?

[Lizwiz]

I used Baretta's Box of Power in a fight against a Spirit of the Snow. BIG MISTAKE!!!!

Every member of my party (active or not) were inflicted with Beast Instinct meaning that most of their magical powers were unusable. I've fought many battles since then and gone back to heal up at the Institute, but the condition is still there.

What can I do? Please help

I've found the answer: You have to let the infected characters die.
When they are revived the Beast Instinct condition is gone.

A strategy that often works.
