Okay, The title says it all, let's think back:
In Tales of Symphonia, Genis gets a "I hate Gels" title if you don't use Gels until after the battle with Pronyma in the mountains.
In Tales of Xillia, If you make it to Xian Du without using gels you get a skit.
In Tales of Vesperia, no items until Barbatos, new title.
So the question if, if you don't have to use gels, how long for until you get a title or skit or something?
