Steel Helm

A Steel Helm is a Helm-class headwear available throughout the Golden Sun series. It is sold in armor vendors at Tolbi in Golden Sun, at Apojii Islands in Golden Sun: The Lost Age, and at Belinsk in Golden Sun: Dark Dawn. This helm can be equipped on all warrior-style Adepts in the series, namely Isaac and Garet in the first game, together with Felix and Piers in the second, followed by Matthew, Tyrell, and Eoleo in the third. It increases the equipped Adept's base Defense rating by 27 points. It can be bought for 3100 coins and sold for 2325 coins.

In Golden Sun when it can first be bought in Tolbi, you really should not buy Steel Helms until, at the very least, after you've redeemed your Lucky Medals at the minigame at Tolbi Spring, which can easily net you large amounts of strong equipment Artifacts, because superior headwear for Isaac and Garet to equip are Adept's Helms and Ninja Hoods. If you can get an Adept's Helm, you would get a helm even better than a Steel Helm and for no money spent at all, but if not, then you can consider investing in a Steel Helm or two.

In Golden Sun: The Lost Age, Steel Helms can first be bought in Apojii Islands, meaning they are available to buy as soon as you get the Lemurian Ship to sail the Great Eastern Sea with. While it wouldn't replace the superior Thorn Crown one of your Adepts might be wearing, it would technically be a very good replacement for the Bronze Helm Piers starts out with if he's still holding it, and still good even if he is equipped with a stronger Iron Helm. But in Champa which is also accessible as soon as the Great Eastern Sea can be explored, an even better Silver Helm can be bought in its place, but even that requires consideration before buying because what can easily be found for free in a hidden chest is the helm Artifact Viking Helm. In this situation, you would only buy a Silver Helm afterwards if you're giving the Thorn Crown to one of your two mage-style Adepts, so that your two warrior-style Adepts can be equipped with the Viking Helm and Silver Helm respectively. In light of all this, a Steel Helm is clearly not the best thing you can spend your money on.
