That type of burst is called valiant rage it's a new battle system thing and, there is three different types attack, magic and healing. Group missions however are a thing exclusive to the reverie corridor in this game where you have to use specific characters as well as certain requirements to complete them, I think using valiant rage was the one for this I might be wrong as I don't fully remember. Hope this helps
