Dragon Bones

Dragon Bones are the main currency on the server. You can trade 4 Bone Shards for 1 Dragon Bone and 1 Dragon Bone for 4 Bone Shards at the Bone Density Scanner Trader at /warp Quest.

Obtaining
Dragon Bones are currently gotten in two ways.

Exchange
At /warp Exchange, you can trade vanilla items such as ores, and shulkers of mob drops for Miners Emblems and Farmers Tokens

Those Tokens and Emblems are then traded for Dragon Bones.

Quests
At /warp Quest, you can find a trader named Questel who will give you Dragon Bones for Weekly Vouchers/Daily Vouchers and a random item (changed around every week)

Seasonal Events
During Seasonal Events, such as summer, it is possible to get a Dragon Bone from killing mobs. During Summer, about every 500 blazes killed yielded a Dragon Bone.
