It can be upgraded with an ebony ingot at a workbench and also benefits from the Daedric Smithing perk, which doubles the improvement.
A Daedric helmet can also be crafted at the Atronach Forge, but it requires a Sigil Stone that can only be obtained via Conjuration Ritual Spell, which in itself requires a Conjuration skill of 90. The Atronach Forge requires the following components to create a Daedric helmet:
- 1 x Sigil Stone
- 1 x Daedra Heart
- 1 x Ebony Helmet
- 1 x Centurion Dynamo Core
- 1 x Black Soul Gem (empty or filled)
- Upon wearing a Dragon Priest Mask and a Falmer helmet, then equipping a Daedric helmet, the Falmer helmet will remain equipped and any enchantments will continue to be in effect.
