I couldn’t verify a reliable answer from the available sources, but in Football Legends / Football Legends X the “4th prestige” usually refers to the fourth prestige tier or rank reset level in the game’s progression system.

What it likely means

  • It is not a universal Roblox term; it’s tied to that specific game’s prestige system.
  • Players typically use prestige to mark repeated progression milestones after resetting or advancing OVR-related progress.
  • Community posts around the game discuss prestige levels and how they work, which suggests the “4th prestige” is simply the fourth step in that sequence.

In-game wording

The exact title or reward for the 4th prestige may differ depending on whether you mean Football Legends , Football Legends X , or another related version of the game. If you want the exact name, I’d need the precise game page or a screenshot of the prestige menu.

TL;DR: the 4th prestige is most likely the game’s fourth prestige tier , not a special separate feature.
