Erebus Armor

An Erebus Armor is an Armor-class item found in Golden Sun: The Lost Age.

In
Erebus Armor is one of the prizes that can be won in the Lucky Medal Fountain in Lemuria. Being an Armor-class item, it can be equipped by Isaac, Felix, Garet, and Piers.

The HP recovery and high Defense rating makes the Erebus Armor perhaps the best defensive equipment available at the time, not to mention one of the most valuable prizes from the Lemurian Spring. Stronger armor isn't found until Jupiter Lighthouse, meaning the Erebus Armor will see quite a bit of use. It may be kept even after better armor is found simply because of the HP recovery. This equipment is worth obtaining multiple copies of.

Cultural references
In Roman lore, Erebus was the name of the underworld.
