Elderbark is a type of wood that is obtained by cutting down Trees in the Briar using an Axe or a Chainsaw. It is also dropped from some enemies in the same biome, and sold by the Adventurer when he is in the Briar. Like Dynasty Wood, crafting recipes that include Any Wood as an ingredient can't use Elderbark as the ingredient. It is, however, a crafting material used explicitly in several other recipes.
