Tales of Rebirth Battle System

[supersonic1453]

So I finally got my hands on ToR, but I would like to know the ins and outs of the battle system.  The game makes it seem like there is a lot of stuff in there what with the battle book being selectable in the main camp menu.  I mainly want to know what the four squares on the character portrait during battle are.

Those 4 Squares are the force cube, basically your TP, however it never runs out (or constantly regenerates) so you can effectively spam tokugi. However a full green square (aka a full FG) would mean that the assigned tokugi would deal maximum damage. When you learn Ougi, you can link onto them by using a tokugi, then for a brief second all the full FGs will change colour to orange, and the assigned ougi can be performed if you press it in time.
