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 an active item before it can be used again.

Some active items cannot appear as hologram due to having one of the following traits:
• 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.
