6Upside Realm

Rule: Gravity. Stage: Mastery.

The realm is cut into 32 x 32 columns, and about a third of them are upside down. Inside one, gravity points up: you, the creatures and the items fall toward the sky and walk on ceilings, up to 16 blocks above the ground. Purple sparks trace the borders. Every 90 seconds the pattern changes, five seconds after a warning; if your column turns back you drift down slowly. Gravity Boots ignore the flips entirely; a Stabilizer or a Flipped Apple keeps you steady for 30 seconds.
