last breath
Last breath is a passive third-slot survival item: qualifying lethal damage leaves its owner on one health, grants brief invincibility and starts an eighteen-second cooldown. It can activate while stowed. The effect is a narrow escape from a lethal hit, rather than a full heal or protection from every kind of death.
How it works
The current functionality section says activation clears negative status effects and provides two seconds of invincibility. Its older item-card description still says status effects are not cancelled. The version history resolves the direction of the change: v2.4.0 added clearing negative effects. Both the old summary and the newer functionality are from the same wiki, so the updated behavior is attributed to that one source rather than described as independently confirmed.
Instant-death effects and most environmental hazards are exceptions. After a successful activation, the user remains extremely low on health once the brief protection ends, and another lethal hit during cooldown is not prevented. Healing items can therefore address a different problem from the survival trigger itself. The article’s appearance cue is a red slash on the torso; the item has no ordinary visible model while selected.
Rivers of blood and certain equipped tags change the activation presentation to a pale flame. The wiki describes this as cosmetic, including the replacement of the Undertale damage sound and bloody decal. It does not shorten the survival cooldown or promise more health. This is why the flame appearance should not be mistaken for a stronger version of last breath. Its principal reference is the Undertale: Last Breath fangame.
