Shadow Gem

Defeat Champion and hold 15,000 Wins. The Escape School door next to the bosses is the published exit into the Gym.

The August 17, 2026 guide says a normal Rebirth spends Wins, sets Bicep, Hand, and Knuckle strength to 0, and keeps Trails plus your remaining Wins. Super Rebirth also resets Trails, Wins, and worlds, keeps Arms, and gives tokens worth +100% Total Strength each while you hold them. Another rebirth listing describes a flat +15% per rebirth and a different keep list, so confirm the button text.

Look for a Codes button on the side of the screen, or open Store and use the Codes control, then press Verify. Each code is once per account. Lists published October 1 and October 2, 2026 disagree about harborking, so that string is not marked active or expired here.

The official experience listing says 28 worlds. A published world index names 19 normal worlds, and only School through Space Center have exit numbers here. The official listing says 28 worlds, so later names are missing.
