Witch Spring R's training system

I was playing witch spring R and got to the point where you can do training stuff and I thought this is a witch game so magic is probably the best thing and i dumped all points into mana. And now I'm stuck in swamp area. Literally every enemy in swamp kills me. And those training timer won't move either so i can't even train. And I've already fought every unique enemy group that I can so I don't get exp from those too. This is really dumb the way this is designed.
