Fallout 76 lingo. Used to denote items or content pieces that are no longer obtainable or playable in game.
Most commonly used to describe legacy weapons, which again are commonly
energy weapons with the 2nd star prefix "
Explosive". Due to bad programming on Bethesda's part,
energy weapons did 100% extra explosive damage, instead of the default 20%.
Keep in mind: not all legacy weapons are considered overpowered, such as the Paddle Ball.
