I couldn't finish 'em. Looks like this's gonna get complicated.
The Nagaraja is an enemy in Final Fantasy IV: The After Years. It is moderately powerful, and will generally attack with physical attacks. If damaged by any magic attacks and not defeated, it will counter by casting Silence on a random party member. Regular attacks and Bio spells work well enough in dispatching them.
Nagaraja" is a Sanskrit word from naga (snake) and raj (king) meaning King of Snakes."
