Pulse grenade (Fallout 4)

Pulse grenades are a type of explosive weapon ordinance in Fallout 4.

Characteristics
Pulse grenades are specifically made to combat robotic foes; upon detonation, an electromagnetic pulse is created that washes over robots and deals damage similar to a regular fragmentation grenade, but over time instead of all at once.

Crafting
By default, pulse grenades can be crafted at a chemistry station. With the Contraptions Workshop add-on, they can be manufactured using an explosives mill.
