Auto-Float

Auto Float is a recurring ability that permanently puts the user in Float status, effectively nullifying all Earth elemental damage and floor traps for that character.

Final Fantasy VI
Auto Float is found on the Cherub Down Relic, and can be equipped by anyone.

Final Fantasy IX
Auto Float is learned from Venetia Shield and Feather Boots. The Feather Boots can be equipped by anyone, but the Venetia Shield can only be equipped by Steiner and Freya.
