The bigger the boom, the better!

Demolition Expert is an Intelligence-based perk in Fallout 76.


The perk increases the damage dealt by all explosions by 20% with the first rank, with subsequent ranks each adding 10%, up to a maximum of 60% with rank five. It affects most thrown grenades, mines, explosive weapons and weapons with the Explosive legendary effect. However, it only affects the primary damage type of a weapon. For example, a grenade that deals two types of damage only has its primary damage increased. This also means the perk does not affect the damage of pulse mines and pulse grenades, as they only deal secondary energy damage.

Behind the scenes

  • Although the perk card art for Demolition Expert depicts remote explosives, these weapons are not available in the game.
  • Prior to Fallout 76 patch, the damage bonuses provided by each rank of the Demolition Expert perk were +20%/40%/60%/80%/100%, but afterwards were reduced to +20%/30%/40%/50%/60% to match other weapon perk damage bonuses.
