The third boss battle in our playthrough, Radahn, whom you probably recognize from early Elden Ring trailers, can be actually challenged at any given moment at Redmane Castle on the Caelid map – it’s East from where you start your adventure.
Despite not receiving a full transformation during the boss battle, which is not technically on two different phases as with Rennala, Radahn is particularly tough to beat, and possibly the first boss that will take you some time to overcome in Elden Ring. Fear not, though, we’re here to help.
