Awaken Draconium Age

Killing a few Ender Dragons will give you access to Dragon Hearts; these can be used to craft Awakened Draconium. This should be used to first upgrade your infusers; once these have been upgraded, you can upgrade all of your armour and tools. It's also highly recommended to craft a staff of power!

Awakened Draconium also is used to upgrade your energy storage and wireless crystals; it can also be used to upgrade any mob spawners you have.
