Instant Death(即死,Sokushi?) refers to an attack that immediately kills its victim regardless of what HP they have remaining. Instant death attacks are recurrent throughout the series; several bosses, including final bosses, are known to use instant death moves and some summons, such as Odin and Yojimbo, can also kill instantly.
In most games attacks that inflict instant death do not display damage points when hit, even if the attack would have inflicted normal damage if Instant Death had not taken effect. In some games, indicators such as the word "Death" or the abbreviation "KO" may appear instead of damage points.
As with the use of curative and resurrection spells, such as Raise, instant death's effect is often reversed for the undead. In some games, using an instant death ability on the undead will heal it to full in the same way that using Raise would kill it, though there are some exceptions, such as the undead in Final Fantasy XII.
Instant death spells generally do not work on bosses, however, exceptions exist.
Due to the Vanish-Doom Bug, in the versions before the Advance remake the Clear status would remove the target's immunity to instant death, meaning even bosses could be easily defeated this way.
