Dullahan

Dullahan is an optional superboss in Golden Sun: The Lost Age and is considered the most powerful enemy in the series. He is located at the end of the optional Anemos Sanctum dungeon. He must be defeated to gain access to the Iris summon sequence. He resembles a headless suit of blue armor.

At the end of the Anemos Inner Sanctum, arrange six blocks to form a bird pattern, then cast the Hover Psynergy while standing on it to be automatically transported to the Dullahan battle. Dullahan stands in front of Iris’ summon tablet, and he will make his challenge:


 * “I am the shadow, the keeper of light. If you want the sun’s power, show me your own.”

Battle stats
Dullahan possesses 16,000 Hit Points which regenerate 200 HP per turn, 300 PP which regenerate 100 PP per turn, 676 Attack, 269 Defense, 241 Agility, 59 Luck, and acts three times per turn. This gives him the award for largest HP, Attack, Defense, Luck, and average stat values of all monsters. He is most resistant to Mercury attacks and his other resistances in decreasing order are to Venus, Mars, then Jupiter. When felled, he yields 15600 Experience and 6775 coins, and you can obtain the Iris summon sequence.

Dullahan’s arsenal of moves are as follows: He can attack physically, cast the Bind, Haunt, Curse, and Condemn Psynergies, and has several extremely powerful monster skills: Formina Sage (he swings a long purple lightning sword through an Adept, doing extreme damage that often downs that party member), True Collide (dark energy does moderate damage to several adepts and adds that damage to Dullahan’s own HP), Element Swap (changes his elemental affinity), and the crippling Djinn Storm (puts all Djinn of all current battling Adepts in recovery; only the Doom Dragon shares this skill). As an ultimate move, Dullahan can freely summon Charon itself, one of the strongest Summon Sequences normally reserved to the player’s party, and it will certainly down several Adepts.

Battle strategy
Going up against Dullahan with a party of anything below Lv. 50-60 characters is generally the same as suicide. At those levels and below, Dullahan may kill your characters before they have a chance to attack. Even at that level, Dullahan will still have his way with them. Many players wait until they reach Lv. 70-80 to fight him. Regardless of the level of the fighters, Dullahan is almost unbeatable if the player relies solely on Psynergy and weapon unleashes, and only when the characters approach Lv. 85-90 do Djinn become truly effective.

The brute strength method generally involves leveling up the party to the higher levels so that the inevitable Djinn Storm doesn't automatically doom your characters. You can combine your higher stats with Critical Hit% increasing items and use continual Unleashes of Megiddo and Legend to do enough damage over time to fell Dullahan. However; this method requires extremely high levels, an ample supply of Potions, and Waters of Life, and will result in a long drawn out battle. Many players who do not level their parties to levels that high generally tend to go all out on him with summons, hoping that he will not use Djinni Storm until the big summons (like Catastrophe and Charon) are fired already, and that the said summons can finish him off. It's a risky strategy, depending on what Dullahan uses, but for most people who don't have a level high enough to simply outslug him can probably have greater chance of success this way.
