I've been using sage so far in story and have a good grasp on it, only usage situation I haven't figured out is Pepsis. It can only be used to dispel a shield into a heal, otherwise it does nothing. Is it just a skill to do just that? If I wait for damage then the shield is gone and Pepsis doesn't work. It seems to be a 50 potency increase for using it though but it doesn't feel good to use.

Everything else is pretty simple. I'm a little shy of 83 before the game refused to let me login for nearly 5 hours today.
