NPCS

NPCS are very essential merchants you can find around Spawn. There are a number of hidden NPCS that sell very powerful items, but I won't list them here unless the community decides to add it as it would spoil the surprise.

Myros, Master of Trade:

Myros is one of the first NPC's you'll likely meet at spawn (Gale Castle) and is very important as he sells the "Order of Exchange" which is an item that give you access to selling items, which is needed in order to make a town. He also sells a number of helpful goods such is the "Rite of Teleportation" a very useful item that will allow you to tpa to your friends.

Earl, City Blacksmith:

Earl is another NPC found at spawn (Gale Castle) he sells a variety of useful equipment sometimes above the vanilla enchantment threshold.

Earl also sells a few utility items.

Ulric, Master of Bones:

Ulric is a very useful NPC found yet again at spawn (Gale Castle) he is a little harder to find than the others as he lies in the dungeon near the entry gate at spawn, you can exchange special bones (Found as a uncommon drop amongst all mobs who have bones) for powerful items below the vanilla enchantment threshold meant to be upgraded upon. He also sells a number of utility items.
