Find the marked altar
GamesRadar directs players to the small red-rune Vegvisir near the starting area; interacting with it marks Eikthyr’s sacrificial altar on the map. [2]
2 / 3
Use the summon item
Attack of the Fanboy specifies two Deer Trophies as the offering. These are the summon items to look for; the linked Deer Hide record identifies a different material. [1]

Watch, respond, then attack
Windows Central describes three attacks: an antler strike at close range, a lightning shockwave after Eikthyr rises up, and a ranged lightning attack from his antlers. [3]
Its combat advice is to watch the telegraphs, avoid the shockwave’s area and attack between blows. It describes shield-and-club combat and a bow as options. [3]
For your first attempt, prioritize recognizing the next attack over squeezing in another hit. A suggested approach is not a promise that every shield will block every attack in your world settings. [3]
