- —Description, Final Fantasy V.
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.
Cursed crown that gradually drains the wearer's HP.
Thornlet is one of the most powerful helmets in the game as far as physical defense is concerned, only being bested by Saucer and Dueling Mask. It provides 38 defense, but also inflicts constant Sap status on the wearer and has no magical defense whatsoever. It can be acquired through a variety of means: stolen from Hidon, metamorphed from Siegfried, Behemoth King (Undead), Daedalus, or Ahriman, and by betting the Force Shield in the Dragon's Neck Coliseum.
Thornlet is a level 99 helmet that provides +500 Bravery, Bravery Boost on Dodge -3%, and Bravery Boost on Block -5%.
Thornlet returns in the prequel, only this time as a level 100 hairpin. It provides -21 HP, +499 Bravery, Bravery Boost on Dodge -3%, and Bravery Boost on Block -5%. It can be traded for at the shop for 101,320 gil, a Leo Recipe, Delicious Fish, and Nethicite.
Thornlet's Japanese name is the Crown of Thorns. In Christianity, the crown of thorns was woven of thorn branches and placed on Jesus Christ during the events leading up to His crucifixion.
