Rubicant was a worthy opponent on the SNES FFII. He was tough enough, and he even healed you before the battle.
As I recall, simply to mess with you, he'd close his cloak and cast Ice 2 on himself, healing himself. Simply out of spite.
But now, on FF4 Advance, he's "Rubicante", with an "e" at the end.
And now, when you cast Shiva on him while his cloak is open, he counters by casting Blizzara (Ice 2) -- on himself.
That's right. Instead of waiting itll his cloak is closed and healing himself, he actually counters your move by attacking himself.
Score one for Square-Enix.
