How to do it:
Stay on B plattform, Hit the right eye to make fenrir turn aside and reveal the left front leg, Hit the Left eye to make fenir turn aside and reveal the Right leg
if you do it right Feniri will fall and you can continue attacking the weak spot (core).
Just a warning if you deliver too much damage and destroy the eye, give up the mission and start over, your panacea will be intact and you can try again.
Good luck!
