Shimmering

Shimmering is a debuff inflicted onto the player when they are submerged in Shimmer, or when the player's fishing pole's bobber touches Shimmer. Shimmering causes the player to sink through solid blocks until an open area of air or liquid big enough for the player to fit (2x3 tiles) is entered. If no such opening is found, the player will sink until they reach the Underworld layer, where the debuff will deactivate and suffocation will occur if the player is still inside a block at this level. While the debuff is active, the player cannot move horizontally or use items, but is invincible to all damage except from that of a boss's attacks. All animations on the player character or mounts will also freeze. This can be countered with the Chromatic Cloak, allowing the player to walk through shimmer without worrying about the debuff. Shimmering will not be applied if under the effects of a Gravitation Potion or the Gravity Globe, and the speed at which you move while Shimmering can be increased by holding a Portal Gun.
