Once you reach level 50 and have chosen a Build for your Druid, you will want to start picking out the best weapons to complement it. The weapons or Legendary Aspects are designed to enhance either a specific Skill, a group of Skills, or your overall damage. Some of these will be best for a specific Build, but many will be good for most, if not all Druids.
