Demolition Expert/Fallout 4

Demolition Expert is a perk in Fallout 4.

Effects
Demolition Expert has four ranks that increase damage with explosives, as well as granting other benefits:
 * Rank 1: Increases damage with explosives by 25%, and allows the player character to craft grenades and mines at any chemistry station.
 * Rank 2: Bonus explosive damage increases to 50%, and the player character gains a projected throwing arc effect when they prime a grenade. This predicted arc extends out to the first solid object it touches, and stops there; that is, it will not predict bounces or ricochets.
 * Rank 3: Bonus explosive damage increases to 75%, and the player character's explosives affect a larger radius.
 * Rank 4: Bonus explosive damage increases to 100%, and any mines or grenades shot in V.A.T.S. explode for double damage as well.
