Project: Gorgon is a 3D fantasy MMORPG (massively-multiplayer online role-playing game) that features an immersive experience that allows the player to forge their own path through exploration and discovery. We won't be guiding you through a world on rails, and as a result there are many hidden secrets awaiting discovery. Project: Gorgon also features an ambitious skill based leveling system that bucks the current trend of pre-determined classes, thus allowing the player to combine skills in order to create a truly unique playing experience.
The Project: Gorgon development team is led by industry veteran Eric Heimburg. Eric has over a decade of experience working as a Senior and Lead Engineer, Developer, Designer and Producer on successful games such as Asheron’s Call 1 and 2, Star Trek Online and other successful Massively Multiplayer Online Games.
At the current time we can't make any Necromancy 'Enabling' Equipment.
You need to be using a least one piece of equipment that have a "Necromancy Gem" which "Enables Necromancy". It should say so on it's tooltip/description
There are many, many different items that include this. Treasure effects for necromancy aren't enough to "Enable Necromancy"
Spoiler:
Lots of items with the Necromancy Gem are just random drops, undead and necromancer probably the most likely enemies to drop Necromancy enabling items. Friendship Gifts from NPC that are Necromancers are likely to be equipment with Necromancy Gems. Be sure to have you Necromancy skill up when your gifting with and completing quests for you Necromancer friends(NPCs).
I've had several items that enable necromancy, amulets have dropped for me many times. 'Something...something Hate' being a common one. Gloves, hood of some sort maybe. They get better of course as you get a higher level and fight better mobs.
