Lichdragon Fortissax is an optionally available boss in Elden Ring, discovered within the Deeproot Depths. To get to Lichdragon Fortissax, you could first defeat the boss on the backside of the ravine within the Deeproot Depths, then work together with the Deathroot discovered there.
After you have interacted with the Deathroot, you’ll be transported to a brand new space the place you’ll combat Lichdragon Fortissax. This boss is a robust foe, so be sure you come ready.
