Old (オールド, Ourudo^?) is a status ailment and spell in Final Fantasy V. It rapidly ages the target (changing their hair color to white, this change is not present when used on enemies), lowering their level. It is caused by the Ancient Sword, Old Time Magic spell, the Blue Magic spells Level 2 Old and Time Slip, the Dark Arts skill Dark Haze, and the Cannoneer's Silver Cannon. When Old is used on characters, all of that character's stats, minus their level, will gradually decrease to 1. When used on monsters, that monster's level and Speed are gradually decreased to 1, which in turn affects that monster's Magic Attack multiplier.

Old can be cured by various means such as a White Mage's Esuna. However the stat changes remain till the end of battle; removal just stops further decay.

The spell Old is bought in Moore for 6,000 gil, is a level 5 Time Magic spell and costs 4 MP to cast. Bone Mail, Angel Ring, and Ribbon make the wearer immune to Old. The player may utilize this ability by catching and releasing a Metamorph or Jackanapes from Exdeath's Castle.
