Crafting are skills that produce items.
Alchemy[]
Alchemy allows players to make potions from plant ingredients they harvest throughout the world.
Blacksmithing[]
Blacksmithing allows you to repair your arms and armor as they become worn or damaged, as well as forge entirely new equipment. It also increases the effectiveness of Repair Kits.
Sagecraft[]
Sagecrafting allows you to do a few different things. You can craft Gems from different Shards you find throughout Amalur, and you can socket Gems into your equipment.
