A less glitchy but longer run, Any% (Restricted) is nonetheless fragile but explores much more of the TUNIC world with a lot less RNG.
Without the ability to ice-grapple to skip segments or clip through walls, this slower category requires the player to ring both bells, collect all major items, upgrade to ATT 4, and ride slow elevators. But doing so crafts a run with lots of its own tech, including multiple lanternless segments, stat upgrade deaths, Muffling Bell sneaking, and encountering all bosses.
It is a great ramp-up to All Relics (Restricted), which is essentially the same until the Heir fight.
