Treasure boxes are scattered all around the Clockworks! It is unknown how or why treasure boxes are inside the depths, but many of them contain goodies for knights to loot.
- Green treasure boxes usually contain heat, crowns, a pickup, or a vitapod when the boxes are broken. Sometimes, a treasure box may contain a crafting material or a token, or even more rarely, a piece of equipment.
- Red treasure boxes hold similar contents, but usually have more heat or crowns than the green treasure boxes.
- Red Treasure boxes marked with a heart will always contain hearts.
On some levels, the color of treasure boxes may appear differently due to colored haze graphical effects.
