Demolition Expert/Fallout 2
You are an expert when it comes to the fine art of handling explosives. They always go off when they're supposed to, as well as causing extra damage.”— Fallout 2 In-game description
The perk causes dynamite and plastic explosives to deal +10 damage and never detonate prematurely. Unfortunately, since all explosives have utterly marginal uses in normal gameplay, the perk is useless.
