A Knight's Helm is a Helm-class headwear available in both Golden Sun and Golden Sun: The Lost Age. It is sold in armor vendors at Lalivero in Golden Sun and at Contigo in The Lost Age. This helm can be equipped on all warrior-style Adepts in both games, namely Isaac and Garet in the first game, together with Felix and Piers in the second. It increases the equipped Adept's base Defense rating by 33 points. Its buy value is 4600 coins and its sell value is 3450 coins.
In Golden Sun when it can first be bought in Lalivero, it probably would not be okay to buy because you can get two stronger pieces of headwear in Lalivero: The Jeweled Crown Artifact that can be bought as an Artifact at the same vendor, and the Warrior's Helm Artifact that can be found in a chest which is the single best headwear for Isaac to equip in the game. And with other equipment artifacts found beforehand such as the Lucky Cap, there seems to be no room for the Knight's Helm to be truly useful if the game has been perfectly played up to this point.
In Golden Sun: The Lost Age, the Knight's Helm's usefulness is practically nullified because it is sold so late in the game in Contigo, long after Felix's party has amassed much stronger equipment such as Minerva Helms from the Lucky Medal minigame in Lemuria and the many possible strong Helm artifacts that can be forged at the blacksmith in Yallam. However, if this game is being played without any data transfer or with a Password that's either Bronze or Silver-level, when Isaac's party joins Felix Isaac and Garet will both be equipped with Knight's Helms, which are of course far inferior to the equipment Felix's party will surely have amassed by that point, so their Knight's Helms should be replaced as soon as possible.
