Sacrificial Dagger

Requires attunement. 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. 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.
