Only two, yes. They didn't want to upgrade it to three after Dende told them that doing so would lead to them having the same drawbacks as the Namekian Dragonballs (ie. can only bring back one person at a time, etc.).

Would it be okay if my character trains using a gravity room at capsule Corp? That was in the show and didn't really require for there to be another fighter to train and get stronger.

...At his current level wouldn't that just crush his body and cripple him? Always assumed that the gravity chambers were for people at around Freeza Saga level powers, of which we are... Not. ^^;

I mean I'm intending to have Chikori eventually go through that kind of intense training (I have an eventual [url=http://moerin-satsuki.deviantart.com/art/Super-Saiyan-Chikori-441028653]end goal in mind for her[/url], after all), but I don't think any of us could cope with that kind of training at the moment really. ^^;
