Sword of Thunder

In the cave to Rhone, on level 5, fall down a hole (any hole). Go to the lower left corner of level 4. Go one square up and one square right. You'll fall down a hole, and the sword will be right there. Best Sword in the game.

Use cursed equipment without the curse

Normally, when equipped with a cursed item (Sword of Destruction, Gremlin's Armor, or Gremlin's Tail), there is a 50% chance the person wearing the item will freeze in battle, rather than act. This is unfortunate, as the sword and armour are the most powerful in the game.

However, there is a way to gain the benefits of the items without the curse.

1. Equip the item(s). This will give you the increased attack and/or defense of the cursed item(s) and inflict your character with the curse.

2. Go to the House of Healing and pay to have the character equipping the item uncursed. This will cost 100 GP per experience level. This will remove the item(s) from your item list and remove the curse, but does NOT cause your attack or defense stat to recalculate.

3. Never again look at your equip screen for that character or gain an experience level. The game does not recalculate the character's attack or defense stats until you look at the equip screen or gain a level, so you do not lose the hefty attack or defense bonus granted by equipping the cursed item(s).

You are free to look in and use other menus, including item and status, or even save and reset, without losing the bonus. However, since leveling up recalculates your attack and defense, you may want to wait until you are ready to defeat the final boss to use this glitch, since it cannot be repeated without finding a new copy of the cursed item.
