Just wondering since when in battle mode I saw a bar labled TP which kept going up and eventually went to 200% I just can't figure out what it is, any help would be appreciated.

TP are points you use to activate weapon skill abilities. You gain tp everytime you hit with a physical attack or get hit. You lose TP when you rest. When TP gets up to 100% you can activate a weapon skill. If you get it up higher (Max is 300%), the weapon skill will do more damage. TP is drained completely when you activate the weapon skill.

That makes sense, thanks Loki.
