Lorenzo's Artifact gun

The Lorenzos Artifact is a unique weapon in Fallout 4.

Characteristics
Not strictly a true unique weapon, it is rather a standard Gamma gun with a unique weapons modification, the Lorenzo's Artifact. This modification changes the weapon mechanic significantly of a Gamma gun; the projectile may significantly knock back enemies (above and beyond the normal stunning effect of a gamma gun).

Unlike the vast majority of radiation weapons, the radiation damage dealt by Lorenzo's artifact is pure damage; it does not do radiation poisoning (in other words, it does not give rads to hit targets), though it is still affected by radiation resistances and immunities.

Note that while numerically a Gamma gun has a higher "damage", the Gamma gun and Lorenzo's Artifact have very different mechanics. The Gamma gun has a core explosion component but is mostly intended to do its damage in the form of rads, which is effective based on the enemy's maximum health. Lorenzo's Artifact trades that off to do direct, unconditional damage. As a result, there will be cases where Lorenzo's Artifact's "lower" damage will actually be much more effective than the Gamma gun, and there will be cases where the Gamma gun will be more effective. See Radiation Weapons for a more detailed discussion.
