Long ago, the power of alchemy allowed people to travel between different worlds through dimensional gates; however, with the collapse of the first great civilization, people lost the means to "jump" worlds. A long time has passed since the great destruction and now people once again are unlocking the mystery surrounding the dimensional gates and adventuring to unforeseen territory, seeking the magical book of infinite wisdom. With the fast paced ACCB system, battle sequences are ordered by cards that represent the characters' action order. The quicker the character, the faster their action turn comes around. An innovative change for Atelier Iris 3 is the introduction of a symbol encounter system. Players no longer randomly encounter enemies, but visually confirm and engage them. Unlike previous Atelier Iris titles, this game adopts a guild quest system through which players can easily accept quests and missions that the guild posts.
