The Bloodworm Helm is an artifact helmet created by Mannimarco, the King of Worms. Improving the Bloodworm Helm requires two Bone Meal and the Arcane Blacksmith perk.
- The Bloodworm Helm has previously appeared in Morrowind and Oblivion. For more information, see the lore article.
- The helm actually increases the magnitude of all spells cast on undead, not just damage-dealing ones.
- This includes the player if the player is a Vampire and then certain Active Effects can and will be increased in magnitude by the helm.
- The helm actually only increases damage dealt by specific weapon types, preventing it from increasing the damage of unarmed attacks or uncategorized weapons like forks, knives or woodcutter's axes.
