Umbra Goggles

The Umbra Goggles are a miscellaneous piece of uncategorized equipment  that was introduced in Golden Sun: Dark Dawn. It is also one piece of the Umbra Gear needed to enter Apollo Sanctum.

Basic Description
The Umbra Goggles increase the wearer's base Defense by 5 points, and also increases the wearer's Mercury and Mars Resistances by 20 points each. As the Umbra Goggles are required for completion of the game, they cannot be bought or sold.

The Umbra Goggles are found in Snowdrift Shrine, and can only be equipped by Sveta.

Analysis
The Umbra Goggles are a unique piece of equipment, in that they cannot be placed in any of the main Armor categories. The Defensive boost, while useful, is fairly minor. However, the Umbra Goggles also grant useful increases to Mars and Mercury Resistance, which stacks when the Umbra Goggles are used in tandem with the rest of the Umbra Gear to grant Sveta a great deal of endurance.

Trivia

 * Although it can't be bought or sold without the use of a hacking device, the Umbra Goggles have been programmed with a purchase price of 3300 coins.
