How do you beat the Neuhkia on Final Fantasy Tactics A2?

Answer 1

First you'll have to destroy the Wisp, enabling you to directly attack the core.

A good tactic would be to send one melee character to the left to wait at the round thing, and the rest to kill the hand. Your magic or ranged characters should take care of the middle spot (where the wisp started off)

Have a character which can either fly or teleport go behind the hand and wait at the round thing there. (if not, then kill the hand first)

(Note: The hand doesn't need to be destroyed, but it makes it easier, especially if you have a lot of slower melee characters)

If you're having a lot of trouble, then you'll need to level up a bit more.
