use and Hold down the "Rally Trumpet" skill to make them Move toward you in the most direct line they possible can.
just watch out fore the Traps on the Flore.
also have heard that if you are Spaced into Priestess, then you can heal them so they move faster, but haven't tested it myself through, a bit indecisive of what class of Weapons/Magic/Holy i want's to play whit...
