When an XP Booster is active, you’ll see several visual indicators:

  1. Timers in various locations display the remaining time until expiration, including the store, play button, tournament screens, and duel options in other player profiles.
  2. XP Icon: An XP icon will be visible on your profile.
  3. XP Percentage: Your profile and match summaries will display the percentage boost and the expiration time.

When the booster expires, all associated timers and icons will disappear, and the boost will no longer apply. You’ll need to purchase another booster to regain the benefits.
