Servers with this tag give players unique abilities that aren’t in vanilla, usually via plugins, datapacks, or mods. Powers are often chosen from a menu, tied to classes/races/origins, or unlocked through progression, and can include things like mobility boosts, spells, elemental attacks, passives, and cooldown-based skills. These servers are commonly built around PvP, factions, RPG, or survival with a power system as the main gimmick.
