Wonder Rod

The Wonder Rod is a truly unique little Rod.  You will find it in Act 3, at the Fork Tower.  It has two special properties.
First, the simpler one: If used while equipped, the Wonder Rod immediately casts the Time Magic spell Return. This has particular value in combination with a party member who's trying to Steal (either a Thief or someone with the Thief Knife equipped), as Reset gives you another chance to steal from the target.
The more complex function of the Wonder Rod is as follows: Whenever it is used to attack, it casts a spell.
The Wonder Rod begins with the White Magic spell Cure, and on each successive attack, performs the next White Magic spell, in order (Skipping Libra).  After cycling through all of the White Magic spells, it goes onto Fire - and from there, the remainder of the Black Magic spells.  After that, it returns to Cure.
Like the Magic Lamp, the Wonder Rod remembers its "location" in its order between battles.  Though this is obtained very late in the game, the Wonder Rod gives you some (very awkward) access to theoretically any White/Black spell you might want.  Take the time to prepare it, and you can bring a free casting of a very big spell like Holy or Flare into boss battles with you; alternatively, it can bring in a key status effect such as Berserk!
Note that GBA players can get multiple Wonder Rods.  I believe they all run on the same internal counter, however, so you can't prepare multiple different spells.
