Imperil (ウィーク, Wīku?, lit. Weak) is a negative status effect from Final Fantasy XIII and Final Fantasy XIII-2. It increases target's elemental susceptibility as well as increases the chance of other debuffs to be more successful. Imperil also increases the chain % points added by spells when adding to the stagger chain.
Its opposite status enhancement is Veil, however, unlike other opposite status effects, Veil will not cancel out Imperil.
Imperil is curable by the item Wax and the magic spell Esuna, as well as the techniques Summon and Dispelga. It can be resisted against with the accessories Pearl Necklace, Gemstone Necklace, Ribbon and Super Ribbon.
Imperil can once again be cured by Wax and Esuna, as well as the Unicorn Horn item and the Esunada spell. It can be resisted with the Pearl Necklace and its Delicate and Durable varieties, and both the Ribbon and Delicate Ribbon.
- The icon used to represent Imperil in Final Fantasy XIII is different to that in Final Fantasy XIII-2. Due to the Water element being removed in the sequel, the water droplet in the icon has been replaced with a gust of wind and the red down arrow was moved to the center for better element icon view.
- In Final Fantasy Record Keeper, some Soul Breaks can reduce target's resistance to one element and while not having an official term, aside of "Slight Weakness" which is a transitional vulnerability between "Normal" and "Weakness", plays have come to refer to them as "Imperil <Element>".
