Shadow in a Bottle

The Shadow in a Bottle is an item added by Shadowrite. When in the player's hotbar, it allows them to jump a second time while in the air, which also resets fall damage. If the player has multiple Shadows in a Bottle in their hotbar, they can jump once in the air for each of them.

Trivia

 * The name, appearance, effect and sounds of the Shadow in a Bottle are a reference to the Cloud in a Bottle from Terraria.
