Sacrificial Dagger (5e Equipment)
From D&D Wiki
Weapon (dagger), rare (require attunement)
Often created by witches to aid in their spellcasting and rituals, Ritual Daggers can be used, when found by others trained in the arcane arts, to mimic a witch's control of their spellcasting to some degree. Their appearance can vary, often reflecting the path its creator chose to walk in her craft.
This is a magical weapon and can be used as an arcane focus if it is attuned to by an arcane spellcaster. It gives its wielder a +1 bonus to spell attack rolls and their spell save DC.
Whether attuned or not, a spellcaster may use the dagger in ritual casting twice per day. By inflicting 1d4 piercing damage to themselves, they may cast the ritual spell with its normal casting time, ignoring the additional 10 minute time requirement that ritual casting normally stacks onto the spell. This ability is refreshed to two uses after a long rest.
