If you need help on leveling up with a Necromancer, look in the beginner section of my guide: The Carnival - A Guide to Pets

But if you are new you probably wouldn’t have it, so just focus on pet items in those slots and the Fettan mask Helmet: https://www.grimtools.com/db/search?query=fettan%20mask&in_description=1&exact_match=0
