Expiration (邪悪なドラゴンの息 Jaakuna doragon no iki, lit. Evil Dragon's Breath) is a Breath weapon in Fire Emblem Awakening, and a Terror weapon in Fire Emblem Echoes: Shadows of Valentia. Both incarnations are used by Grima. In Awakening, it can manifest as Grima releasing a large ball of fell breath or dark spikes rising from the ground to strike the target, much like Idunn's Dark Breath.
- The English name of this weapon is a play on words, as the word expiration can mean both "death" and "breathing out".
- Expiration is the only weapon in Awakening to have a maximum range of 5, making it the second highest ranged weapon in the game after the Mire tome.
- Despite being classed as a Breath weapon, and to substitute for the lack thereof in the convoy, the game internally stores the weapon under Stones.
