Ring of Covenant is a consumable in Glacier's Laboratory, a mod for The Binding of Isaac.

Spawns a permanent hologram projector.

Each hologram projector can create a specific active item hologram, pressing drop button while touching it will trigger respective effects.

Once the effects are triggered, hologram projector needs to be recharged like a active item before it can be used again.

• Has 0 charges.
• Has a special charge type.
• Has quest tag or hidden tag.
• Has complex, extra or hidden mechanics that cannot take effect by simply using the item.

• Download Glacier's Laboratory from the Steam Workshop.
