Is this where heal skill comes in? Stabilization? If not, then pick something else for an exchange for another Cure. And...we are in trouble, by one. With that last lost HP by Talarin, I now have enough spells to exchange to get him to zero, but no further. And Denkou would remain at zero. So...I really hope I can stabilize Talarin without using Cure, but since my comp is off for the night and I'm on my phone, I can't check.
Guess I'll find out in the morning!
