Foolish child! Need it beaten into you, do you?
~ Elusid

Elusid is one of the enigmatic grotto bosses from Dragon Quest IX. He's a clever knowledgable dragon that seems to know the secret of the grottoes' changing nature: Apparently they reflect what's in the mind of the explorer. This monster specializes in casting spells which can be easily deflected by any barrier ones. He can also strike with the grimoire that he holds.
