Demolition Expert (Fallout: New Vegas)

Demolition Expert is a perk $$

Effects
Each rank of this perk increases damage dealt with all weapons governed by the Explosives skill by twenty percent, up to a maximum of sixty percent.

In theory, the perk would also affect the G-28 grenade launching system and M-235 missile launcher, but those weapons are unavailable to the Courier. Likewise, it would have affected the Meat Mine, Nellis Munition Shell, and Stun Grenade, all of which are weapons cut from the game.
