Resources are used to craft equipment. There are two kinds: regular resources and special resources.

|Wood||Sawmill||Hardwood||Fine Woods Inc.||Jewels||Fine Jewels & Co.|
Also known as rare resources or special items, special resources are materials required to craft certain equipment. They are obtained by sending Heroes on Resource Quests from The Inn. You may hold a maximum number of each special resource equal to your storage capacity. For example, 50 storage capacity can hold at most 50 of each special resource. Exception: special resources and equipment obtained from opening chests are allowed to overflow the storage capacity.
Each special resource has a level. Following the Halloween 2015 update, players cannot see a special resource on the trade house if the resource is more than 5 levels above their player level (see forum post). For example, a player level 9 can see up to Iron Carapace (resource level 14), but not Wyvern Wing (resource level 16).
