Elijah's advanced LAER is a semi-unique weapon in the Fallout: New Vegas add-on Old World Blues.


This weapon is identical to the LAER in appearance, but differs in ammunition capacity by having five fewer shots per magazine and a slightly increased rate of fire. This gives it a higher damage-per-second (DPS), but also makes it much less durable. Given the original variant's fragility, its condition is a major concern, especially when using over-charged, optimized, or max charge ammunition.


Elijah's advanced LAER can fire a total of about 245 times using standard cells, the equivalent of 17 reloads (or 13 reloads when modified with the auxiliary recharger chip), from full condition before breaking.

  • As the name suggests, both of these LAERs were modified by Elijah during his stay in Big MT.
  • The weapon's condition only has 50 HP, so it degrades incredibly fast. Using bulk ammunition can prolong this weapon's life, at the cost of reduced damage.
  • This weapon can prove to be effective if companions use it, as the weapon will never decay (unless if the weapon is damaged and/or disarmed by any enemy). The companions Arcade Gannon and Veronica Santangelo will use the weapon effectively, as they both have the Energy Weapons skill tagged.
  • This weapon is one of the rarest non-unique weapons in the game, with only two being obtainable.
  • With the Built to Destroy trait and max charge ammunition, this weapon can go from perfect to poor condition in an unprecedented 84 shots.
  • Fully upgraded, this weapon makes use of special microfusion cells more effective, as it refunds 25% of the cells used, and its high per-hit damage makes better use of optimal charge microfusion cells than any other energy weapon.

Behind the scenes

Elijah's advanced LAER uses the same electric beam weapons technology also developed in the Secret Vault in Fallout: Brotherhood of Steel.
