Grognak the Barbarian (Fallout 4)

Grognak the Barbarian is a perk magazine in Fallout 4 that gives the player character ranks of the Barbarian perk.

Background
Grognak the Barbarian is a series of comic books published by Hubris Comics. The comic books relate the adventures of the main character Grognak's adventures.

Gameplay
The magazines consist of a 10-issue run that each gives an additional rank of the Barbarian perk, which raises the critical damage of unarmed or melee attacks by 5%. This stacks together to gain up to a 50% increase in melee or unarmed critical damage, if all comics have been found.
