Mad cap

The Mad Cap (Mysterious hat in the NES and Magic helmet in the GBC) is unique headgear in the early entries in the Dragon Quest series.

Appearances

Dragon Quest II

The hat reduces MP consumption in battle by 25% (rounded up) and provides Defense of +4 (+8 in the remakes). They are dropped by Tyrannodactyl, Pazuzu, and Hargon with a rate of 1/128, and 1/16 times by Liquid Metal Slimes in the remakes. Fortunately, the GBC and Phone Version has one obtainable in a chest at the Cave to Rendarak. It is also the only helmet equipable by the Princess of Moonbrooke

Dragon Quest III

The hat reduces MP consumption by 25% (rounded up) as before, and provides Defense of +8. They are dropped by Firn fiend with a rate of 1/128, and may be equipped by priests, mages, and sages. The MP reduction rate can be combined with the Glombolero for extra-economic casting. Because of the minuscule drop rate and the absence of any chests that contain the topper, it is strongly recommended to bring a thief when attempting to snag one.
