Know Your Enemy

Know Your Enemy is one of the companion perks in Fallout 4.

Obtaining
To gain the perk, the Sole Survivor has to reach maximum affinity with Paladin Danse and side with the brotherhood when building the relay to infiltrate the institute, which is possible after completing his personal quest, Blind Betrayal.

Siding with the Minutemen or the Railroad before completing Blind Betrayal will lock this perk away.

Effects
The player character deals 20% more damage against ghouls, super mutants and synths.
