Thornlet (いばらのかんむり, Ibara no Kanmuri?, lit. "Crown of Thorns") is a recurring helmet in the series. It is oftentimes one of the strongest helmets in terms of Defense, but at the cost of constantly draining the wearers HP at a rapid rate. It is usually recommended to have something with Auto-Regen to counter the Sap effect of the Thornlet.
Thornlet is the most powerful helmet in the game, boosting +20 Defense and +5 Magic Defense, but at the cost of +4 Weight, -5 Magic, and constant Sap status. It also prevents Sleep, and can be acquired either by finding in the Pyramid of Moore or Sealed Temple, or by stealing them from Lamia Queen.

It provides 38 defense, but also inflicts constant Sap status on the wearer and has no magical defense whatsoever.
