Final Fantasy IV Advance - Dwarven Castle - Golbez (Rematch)
After defeating Calcobrina, the dolls will retreat, and Golbez will appear to challenge you to a rematch. During the rematch, Golbez will lead off by unleashing a cursed aura that paralyzes your entire team. After that, Golbez will summon the Black Dragon to instantly bring down everyone except for Cecil. As Cecil is about to be target, a Mist Dragon will come to your aid and unleash an icy wind, defeating the Black Dragon. It becomes evident that Rydia summoned the Mist Dragon and will cure Cecil from paralysis. Golbez will cast some spells that will do heavy damage, so if you have any curing and reviving spells, use them wisely. After defeating Golbez, Rydia will be grown up, and she will confess that when she was swallowed by the Leviathan, it dragged her into a phantom world where time passed swiftly, causing her to mature. Rydia will then rejoin your party. However, Golbez will steal the crystal before vanishing somewhere.
