Earthsplitter is a recurring skill in the Dragon Quest series.
Making its main series debut, it is learned by the Luminary after Elder Eegoltap awakens his sleeping powers. It costs 16 MP to use, and deals 90-230 earth damage to all enemies, while dealing 200~240 earth base damage and 400~440 earth damage if the Sword of Light or one of its reforged forms is equipped. When the Lost Lovers side quest is completed, its MP cost rises to 32, and deals more damage based on his strength.
The first Coup de Grâce in the Avan sword-style.
