Restorative items:

 * Mallet (60 G): cures amnesia;
 * Maiden's kiss (500 G): cures toad;

Permanent items
These items can be used repeatedly in battle and don't get used up. They are considered by some a prototype of the more famous Summons that are introduced in Final Fantasy 3 and became a staple of the Final Fantasy series.
 * Gaia drum: found at the bottom of Tropical Island, bought at the top of it; it casts "Earthquake 10"; it is actually used up after about a hundred usages;
 * Wyvern: found at the entrance of the Cyclone; it casts "Blaze 7"; it is also a key item.

Consumable items
Mostly won from defeated enemies or sometimes found in chests.

Key items

 * Canoe: allows to travel on freshwater (rivers and lakes, but not open seas);
 * Snowcraft: allows to travel on the glacier;
