Red Eagle’s Bane is the true form of Red Eagle’s Fury – the sword of the ancient Reach king Red Eagle, reawakened in his tomb. It’s built to send the undead running.
How to get it
In Rebel’s Cairn during “The Legend of Red Eagle”, place Red Eagle’s Fury in the slot on the pedestal. This opens Red Eagle’s hidden burial chamber. Once you’ve defeated Red Eagle himself, take the sword back from the pedestal – it has now become Red Eagle’s Bane.
Enchantment
Undead up to level 13 are set on fire and flee for 30 seconds. Great early-game insurance in draugr-filled barrows, less so later on.
Smithing
Steel Ingot with Arcane Blacksmith. As a honed draugr weapon it benefits from Dwarven Smithing.
Trivia
The sword gets a brief mention in the book The Red Curse, Volume 2.
