In Uncharted 4 multiplayer, the supernatural power-ups are called Mysticals.
Mysticals are special abilities inspired by supernatural artifacts and legends from the Uncharted series. Rather than functioning like ordinary weapons or equipment, they give players dramatic battlefield effects. Wrath of El Dorado, for example, attacks nearby opponents, while the Cintamani Stone can heal the user and teammates.
The multiplayer system is built around more than Mysticals: players can also summon Sidekicks, including Hunters, Saviors, Snipers, and Brutes. Treasures earned in matches help players purchase weapons and other items. This makes Mysticals one part of a broader loadout and support system rather than the name for every special multiplayer feature.
A common mix-up is calling them artifacts, relics, or boosters. Those words describe the theme or a possible gameplay effect, but “Mysticals” is the game’s official category name. Uncharted 4 launched in 2016, and its online multiplayer was available on PlayStation 4.
