Ritual Dagger

Ritual Dagger is a Colorless Card that can only be obtained from The Nest Event.
Killing an enemy with Ritual Dagger will increase the card's damage by 3(5) for the rest of the run. Using it will exhaust it, whether it kills an enemy or not.
Some enemies do not count for kills to increase Ritual Dagger's damage, listed below under Interactions.
