FALLOUT 4 ONE-SHOTs only challenge is broken?

Can you beat Fallout 4 killing foes with only one hit? Challenge accepted : ) In the video I’m trying to beat that challenge on survival difficulty using top-tier one shot weapons and perks as well as some funny tricks for most tough enemies. The list of rules below: - The player can hit foe only once, if the foe did not die, challenge is failed. - AOE damage must kill all opponents it hits. - Damage from environment and other NPCs do not count as player’s hit. - Multiple hits performed in one fraction of time counted as one hit, as example: legendary two-shot weapons hit, grenade explosive which detonate land mine. Feel free to ask any details in comment section : ) Mods used: Scrap Zapper, Survival quick save.
