The Elder Lion enemy from Elden Ring appears inside enemy camps in Nightreign. This boss features quick biting and slashing attacks, and can jump around while swinging its arm-blade around. It is best to isolate the Elder Lion from other enemies that can stagger and distract players. Dodging behind it and waiting for its combos to finish will allow players to safely maneuver around the fight.
Consider fighting Elder Lion at level 3+.
