In this exercise, you will build out a domain model for a MMORPG called EverCraft for the company Blizzards of the Coast. Just follow the requirements below, pairing and test driving your code of course, and have fun.
This document and template projects for several programming languages can be found on-line at https://github.com/PuttingTheDnDInTDD/EverCraft-Kata.
May all your rolls be 20s.
