Usually, when a legendary item is included in a quest, it will be shown in the quest screen, but I have also recovered legendary weapons and outfits on the intermittent exploration quests. Some quests will include Legendary Weapons and Legendary Outfits as rewards for the quest. You can get Legendary Weapons in four ways: 1) Finding legendary loot when exploring or on quests. This also means that you cannot craft the same Legendary Weapon repeatedly in the Weapon Workshop to get the achievement. E.g., if you have already collected The Lone Wanderer pistol and you later get a Legendary Dweller that comes with the same pistol, the achievement does not credit the second instance of that weapon. This achievement is for collecting 20 different Legendary Weapons.
