The Island King is a melee weapon used by Monica Raybrandt in Dark Chronicle. It builds up from the Griffon Fork, the Sword of Zeus, the Shining Bravado or the 7th Heaven. It doesn't come with any ability. The Island King is Monica's most powerful sword in Dark Cloud 2, with Dark cloud as 2nd best even though it has better maximum elemental stats. Its very high Beast, Exorcism and Scale stats will kill undead monsters, beasts and reptiles in no time. Its high Smash stats will increase the damage done to armored enemies, though the Island King isn't quite as powerful as Max's ultimate hammers.
Although it has a slow four-hit combo, like the Sword of Zeus, Island King's brute attack power is unmatched by any other sword. This sword can't be found in chests. It's only obtainable with the build up system. It cannot be invented or bought.
