Breaks?!? What are these "breaks" you speak of?
I just spent 14 HE to finish getting my 3rd Medusa. I figured I was close enough and had so much Enhance Material for her, why not. Plus I won't get much time tomorrow to try and do a run for it. I managed to figure out how to work around with the different friend Eidolons and keep winning. Now I can get her raged in 1st turn and into stun before her 2nd OD and kill her either in stun or right after she gets out of it.
Andromeda is now lvl 12. Man these Legendaries take a while lvl.
