Boss Gobby

Boss Gobby is a boss that is encountered at the end of Rydia's Challenge Dungeon in Final Fantasy IV: The After Years. It is accompanied with three Minion Gobbies.

Strategy
The Boss Gobby will order the Minion Gobbies to attack with a physical attack, but will do minimal damage if your party is in the back row. Outside of ordering his minions to attack you, Boss Gobby will not attack otherwise unless you attack him. If the Boss Gobby is attacked, he will automatically counter with Black Magic like Thundara, Bio, or even Firaga. It is recommended not to fight him during a Full Moon so his Firaga will not do high damage. Fighting him during the Waxing Moon phase will lower the damage his spells will do (it will also lower your spell damage, though you will still do considerable damage). If all of the Minion Gobbies die before the Boss Gobby, he will use Protect, Shell, Haste, and Curaga to bolster himself and make your life more difficult. It is optimal to kill only two of the Minion Gobbies to reduce the damage coming to your party. It will also benefit you to have access to Rydia's Bio spell. One hit from one of Rydia's Bio spell should be enough to kill a Minion Gobby if you target it specifically, and it will do lots of damage to Boss Gobby if you make him the sole target. Attacking all the enemies at once with the Bio spell is not recommended, as a counterattack from Boss Gobby and ill-timed attacks from any remaining Minion Gobbies might kill off your party. Luca can use her Big Throw to deal damage while remaining safely in the back row. Use Hi-Potions to heal when your hit points starts to get low. A Firaga can do up to 900 damage or more during phases that do not affect black magic, so it is best to keep your hit points above that as much as possible. If Rydia and Luca are at around Level 40, two or three hits with the Lightning Brain Buster should kill him. You will still have to kill the Minion Gobbies if you left any alive when you defeat the Boss Gobby.
