Grognak the Barbarian (Fallout 4)

Grognak the Barbarian is a perk magazine in Fallout 4.

Background
Grognak the Barbarian is a series of comic books published by Hubris Comics in the mid-21st century. The comic books relate the adventures of the titular character in a prehistoric world.

Characteristics
The magazines consist of a 10-issue run that each give you 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.
