Laser Gun (Fallout 4)

The AER9 laser gun is a weapon in Fallout 4. Variants include the laser pistol and laser rifle.

Characteristics
Compared to the similarly modified Institute lasers, laser weapons offer superior damage with a slower rate of fire, however can do more DPS when fully modified. They can be found throughout the Commonwealth, but are particularly popular with the Brotherhood of Steel and the Gunners.

Variants

 * Old Faithful, a special laser pistol that does double damage if the target is at full health. It is sold by Arturo Rodriguez in Diamond City.
 * Survivor's Special, a special AER9 laser rifle that deals more damage the lower your health is. It is a potential reward for completing the quest The Lost Patrol. It is also possible to steal the item from Paladin Brandis, before the The Lost Patrol quest ends.
 * Good Intentions, a special AER9 laser rifle that, on critical hits, causes targets to frenzy. It is carried by Clint.
 * Prototype UP77 "Limitless Potential", a unique laser pistol, can be found by pressing a button to open a hidden room: Requires Lockpick level safe, in the University Credit Union. It has unlimited ammo capacity and never requires reloading, the magazine size is equal to all fusion cells currently in inventory.
 * Righteous Authority, a special AER9 laser rifle, given as a reward for completing the Call to Arms quest. Its critical hits do double damage and the critical meter fills 15% faster.
 * Wazer Wifle, a special AER9 Laser rifle similar to the Prototype UP77 "Limitless Potential", it is given as a reward for completing three unmarked quests for Shaun after ending the main quest with any faction.

Locations

 * Commonly used by Gunners

Bugs

 * Occasionally the reload animation will not add a fusion cell, thus leading to an invisible magazine.
