Defeat ??? as EveSacrificial Dagger

Sacrificial Dagger is an unlockable passive item.

Effect

• Spawns a sideways dagger that orbits Isaac, deals high damage to enemies on contact, and blocks enemy shots.
  • The knife deals 15 damage per tick or 225 damage per second.

Notes

• The dagger has a considerably larger hitbox than other orbital familiars, making it easier to use both offensively and defensively.

Trivia

• In the original Binding of Isaac, Sacrificial Dagger rotated upright, while in Rebirth it now orbits on its side.
• This item is used in Challenge #4 (Darkness Falls).
• It does the highest amount of contact damage out of all orbitals.
• While the in-game name and Steam achievement name says 'Sacrificial Dagger', when unlocked, the in-game text shows 'Sacrificial Knife'.
