This is the second berserker in my NG+ run. As you can see, his lifeline is green, which means this is a relatively easier berserker and a lower level boss compared to Kratos's armor and weapons level.
I am stumped that using the relic does not stun him or prevent him from attacking me. That should have made it much less of a fight but especially with the "Hilt of Skofnung" relic usage, there is so much of onscreen activity with the 12 swords, reading the screen becomes a bit of a struggle.
