Huh. I just had a brainstorm. (Well, more like a thirty-second downpour, but whatever.) Ayla and Robo, because one existed before contact with the Frozen Flame and the other has no animal genetic code, are pretty much at the same level of progress as the Enlightened who were forced to siphon their magic from Lavos. By utilizing the magic of the other party members in Double or Triple Techs (like Ice Tackle or Giga Volt or what have you), they can basically channel the magic like they were born with the ability. They'd have to be channeling it through something, though, because I don't think Ayla would find it pleasant to be electrocuted every time she went in for the kill.
So, basically the Enlightened Ones are idiots, since a) the evolved creatures of the group (Chrono, Lucca, Marle, and Frog) have the ability to use no-strings-attached magic like the Zealian Royal Family, and b) even Ayla and Robo can use magic to the same extent the Enlightened Ones can, with a mediary (whether it be Lavos or one of the group with innate ability) required to channel the force.
