Chris' classic strategy of "camp the central teleporter" is unlikely to work in this battle because
(1) Jake and Duke have been here before. They know the place.
(2) The path to the central teleporter is shorter from the entrance than from the upper chamber, where I would expect Chris' team to start.
Also, Jake's still got that invisibility spell, so any stealth or sneak attack advantage would go to us.
Isa is essentially countered by Fou-Lu, who can fly in dragon form and who has access to the learned technique Spirit Blast, a melee tech that ignores defense.
Further arguments forthcoming when I stop having the attention span of a five-year-old, probably.

another place and time, without a great divide, and we could be flying deadly high
