Open Helm

An Open Helm is the first Helm-class headwear available throughout the Golden Sun series. It is generally the first Helm-class gear available to the player.

In and
It is sold in armor vendors at Bilibin and Imil in Golden Sun. The Open Helm is a pretty good upgrade to the Leather Caps that Isaac and Garet are probably wearing, and is worth your generally low amounts of funds you would most likely have at that point. From a financial perspective, they are much better than the Wooden Cap, which costs twice as much yet only gives one more point to Defense. It is also sold at Imil.

It is sold in armor vendors at Alhafra and Garoh in Golden Sun: The Lost Age. An Open Helm could be considered for Felix once the party reaches Alhafra, but be advised that in the town Mikasalla, which can be entered even before Alhafra, the far stronger Bronze Helm is sold for 600 coins, so it is very likely a much better idea to shop there. It is also sold at Garoh.

In
It is sold at the armor vendor in Harapa in Golden Sun: Dark Dawn. The Open Helm is a likely upgrade from any Leather Caps Matthew and Tyrell may have. Given that the player will not have access to stronger headwear until reaching Kaocho at the least, Open Helms are an excellent choice. Should the player buy Open Helms, they can pass over the Wooden Caps in Kaocho, which would only be incrementally stronger, for the Bronze Helms in Ayuthay.
