Elgo ( boss ) Elgo is the second - to - last boss in " Final Fantasy Dimensions " . The battle is divided into two parts . As the Warriors of Light and Darkness reach the Edge of the World of Nil , they come across Elgo sitting at his throne who explains that he is the Emperor of the Avalonian Empire , and was seeking the crystals out to defy death and rule to the end of days instead of gaining temporal power . The heroes learn that the crystals caused a dimensional shift and divided the world so as to remain safe from Elgo . The Warriors refuse to hand the crystals over , causing Elgo to show them the Power of Nil . Battle . Elgo is fought in two stages . In the first he uses mostly high level magic . He will at first use Flare , Holy and Comet , and continue either of them with Slice n ' Dice . His spells can do several thousand damage , around 3000 – 4000 each , and Slice n ' Dice can hit for above 1000 . At this stage he infrequently counters attacks with Slow . After half his HP has been depleted the second stage starts with a sprite change and he gains access to Pandora ' s Box , which allows him to employ one of three high level elemental magic to hit the entire party . Neutrino deals fire damage , Axion deals ice damage and can inflict Stop . Neutralino deals lightning damage and can stun . Elgo ' s Magic Blade command from the Red Mage job uses the likes of Arcish Slash and Freezing Slash as a stronger Slice n ' Dice . He counters attacks with Gravity , which halves a character ' s HP . Later on he casts Meteor and Ultima , the latter of which can deal 3000 damage to the party with Shell on . Strategy . The party should be well - level ed ( 70 + ) and geared as this boss can be difficult due to his high HP since the last boss and his deadly arsenal of moves . The player should come prepared with at least two healers . Seers are a good choice and preferably equipped with the Hermes Sandals found in the dungeon . Other preparations include learning some power moves like Saber Dancer , which can be learned in Castle Lux , as well as some of the game ' s most powerful Fusion Abilities like Mighty Wall , Hastega , Final Heaven , Midareyuki , and Phantom Rush , as they can inflict great damage . Supplies like Dry Ethers or X - Potions are also a good idea . The player should set as many buffs as possible . One healer should focus on healing while the other buffs , as Elgo can kill characters quick if defenses are not ready . The attackers should use their strongest attacks and use an Ether or a Dry Ether if they run out of MP . For the healing tasks Seer are a good idea due to their high INT and MP values . Since the player is likely to consume a high amount of MP , the Warrior and Monk , while durable , are not good as their MP values are low . The player should waste the least time on restoring MP as possible and spend more time on the offensive . Once Elgo hits the 50 % HP threshold he will become more aggressive with his attacks using Pandora ' s Box for major elemental damage . Gravity can be annoying since it can be followed with a strong attack , so the player should keep both the healing and buffs at all times . The Hermes Sandals helps , as it almost guarantees the healer can heal between attacks . Tetra Bangles can help in keeping the damage from many of his attacks at bay since they fall on the categories the accessory protects against . At near 3 / 4 of his HP gone , Elgo may use Ultima , his strongest attack that is likely be fatal to those without any protection . As long as the player keeps the high damaging attacks going Elgo should fall soon , as most of the difficulty comes from Elgo ' s strong attacks while being resilient .
