A few things from reading this thread. Went back and "reforged" some items I picked up like the ribbon for Jade, and now she recovers a whopping 6MP per turn instead of three. Damn, was that worth it. Also, reforged some of my agility items I picked up as well, and the platinum Greatsword. Hero's attack power is crazy good now, though I will probably transition to sword and shield when I get a few more medals and can get the falcon sword.
I also "reforged" the Academy uniforms since my women characters all wear them, and Erik has two pair of Robber+3 gloves to boot. Also, if things seem "too easy" I just don't do much fighting - I run through the area picking up materials, and fight monsters I haven't seen before, or that have specific items I want to steal from time to time. As for Tentacular, that was the fight with the power of Sylvando - he's amazing for boss battles. His Hustle Dance (and Oomph), and Jade's multi thrust made that fight doable at lower levels
