Level 5 Death

Level 5 Death (レベル 5 デス Reberu 5 Desu) is a recurring Blue Magic spell in the Final Fantasy series. It consists on dealing instant KO to all enemies whose level is a multiple of 5 (ending in 5 or 0). One difficulty in obtaining this spell is that the character learning it must not actually die from the spell, which may pose problems for players who have a relatively even-leveled party.
