Minerva Helm

A Minerva Helm is a Helm found in  and Golden Sun: Dark Dawn.

In
In The Lost Age, it is one of the prizes that can be won in the Lucky Medal Fountain in Lemuria, and can be equipped by Isaac, Felix, Garet, and Piers. At first glance, the Minerva Helm is a valuable piece of equipment, since the Adepts that can use it have low PP ratings in their default classes. However, increasing maximum PP by 20 points pales in comparison to the PP multipliers of equipment like the Adept's Helm. Even more valuable is the PP recovery of the Crown of Glory, another prize from the Lemurian Spring, which essentially gives the wearer limitless PP. Still, these pieces of equipment offer less base defense than the Minerva Helm (especially in the case of the Adept's Helm).

In
In Dark Dawn, it is found in a treasure chest in a house at Iceberg Outpost, and can be equipped by Matthew, Tyrell, and Eoleo. The Minerva Helm is slightly more useful in Dark Dawn, where it is the only headgear available to Matthew, Tyrell, and Eoleo that outright increases their PP. However, the Lucky Cap, while weaker, restores 2 PP a turn. The cursed Thunder Crown also regenerates PP, at the rate of 4 PP per turn, and is only slightly weaker than the Minerva Helm. Depending on the playstyle of the player, they may prefer to equip the Gloria Helm, which regenerates 10 HP a turn, or make use of the Warrior's Helm, which increases Earth Power and the chances of a Critical hit while possessing a weaker Defensive rating.

Origins
In the Roman Pantheon, Minerva was the equivalent of the Greek Athena, being the goddess of Warriors, Wisdom, and Medicine, as well as other assorted things.
