Near the end of a Seven Wonder Quest, there is the Tetra Force. The Tetra Force is a special 'thing' that allows you further develop your Growth panels. With Tetra Force you can level up nearly infinitely. Tetra Forces are similiar to Save Points, once you complete a scenario quest you save and use Tetra Force to develop your Growth Panels. Tetra Forces do not appear at all Seven Wonder Quests however, each quest for a different character's story can vary, for example one quest in one Laura's story that has a Tetra Force may not have one in Judy's story.

Seven Wonder is a vital part of your character's storyline; making your Seven Wonder as a side-quest will usually result in No Tetra Force, which means that you should that take all Seven Wonder quests as possible. The total LP of your party must be lower than the first time you use it in order to reuse the Tetra Force. In other words, that the more times you use the same Tetra Force, the lower your LP must be to use it again.
