There are many resources in Eastward and some of them are not properly explained to you as you play. One of these is gear parts. This resource is extremely vital as you progress through the game.
Gear parts are used to upgrade your gear like your bomb box or ammo box. For example, this allows you to upgrade your bomb box. You can either increase its carrying capacity or upgrade the bombs themselves. For such an important resource, you are probably wondering where to find them and if you can farm them.
Players can find gear parts throughout Eastward in chests. Unfortunately, because of this, you cannot farm them. This means you will have to use them tactfully when upgrading your equipment. Upgrading your equipment can be done at shops all over Eastward. It requires a mix of salt and gear parts to do so.
While you cannot farm gear parts, you can still make sure you collect as many as you can. Using the treasure radar and keeping your eyes peeled for hidden treasure chests is the best way to maximize how many gear parts you get. Gear parts tend to be in harder-to-find treasure chests, so it can be easy to miss them.
