I took advantage of the double xp weekend to move Froggie up. She turned out to have four green quests that gave her the xp she needed. She is now hanging out in the Butcherblock Mountains seaport area, and successfully killed a couple of things.
I think she is still an awful fighter, but I would normally have a character by now who could make potions or armor that would help even a weaker fighter advance.
I've been gathering but not crafting at all. I'll need to stop and learn that so I can advance. I must also be missing some other key to her character that will help.
At least she isn't a voodoo doll any more.
