NulDeath (バマジク, Bamajiku?), also known as Death Force, is a recurring Status in the Final Fantasy series. It protects the afflicted from instant death spells, and is always cast through the spell NulDeath.
NulDeath appears as the status that can be placed upon the party by using the spell NulDeath, also known as ARUB and NulMgc. The status gives immunity to instant death attacks.
Death Force can be cast through the Enemy Skill of the same name. It gives protection from Instant Death until the end of battle. Despite Death Force being an enemy ability, the lone enemy that casts Death Force never uses it in battle, thus the status never afflicts enemies unless Death Force is deliberately placed on an enemy by the player.
If Death-sentence is cast upon a unit with the Death Force status, the timer will count down, but when it reaches zero, nothing will occur since the Death-sentence status chains into the Death status which the unit is protected against. Death Force does not protect the player against the Death Joker Limit Break. Death Force is removed by DeSpell or White Wind.
