Knight

41.0

The Knight is a special type of enemy that can only be damaged from the brain in the back of their heads. However, explosions or shots that pierce enemies, such as Brimstone or Cupid's Arrow, will allow damage to be applied from any direction. The Knight normally walks around in random directions, but once the player is directly in front of it, it will dash towards the player at a slightly faster speed until it hits a wall.

Variations

Selfless Knight

41.1
Chance to replace Knights

The Selfless Knight has a similar appearance to an ordinary knight but has an Isaac face on its back instead of a brain. This version is much faster than the normal version, especially while charging.

Floating Knight

254.0

The Floating Knight is similar to the ordinary Knight but can fly over all obstacles. It also moves slightly slower.

Bone Knight

283.0

The Bone Knight is similar to the ordinary Knight but leaves behind a short-lasting trail of damaging Red Creep, making it much harder to attack its vulnerable side. Its charge is faster than an ordinary Knight, but not as fast as the Selfless Knight.

Notes

• The Knight is a monster in two segments: an invisible, invincible "shield" segment that leads the way and the visible "body" that follows close behind. The shield takes no damage and partially covers the body, stopping shots that would damage it; but piercing tears and explosions hit both the shield and the body, defeating this defense.
  • Sometimes when a Knight changes directions it appears to pause for a moment; this is because the shield segment is moving past the body segment, and the body won't move until the shield moves away from it, the same way the trailing segments of Larry Jr. or Buttlicker chains behave.
• Prior to Booster Pack #5, the Knight and its variants were briefly invulnerable when they spawned, or when you entered the room they are in. They would become vulnerable when they started moving.
  • In the original Binding of Isaac, Knights were completely vulnerable when they spawned; the shield segment did not cover the Knight's front until it started moving, so you could shoot it in the face for damage as soon as it appeared.
• Flush! does not work on Knights.
• Items that provide a fear effect (like Dark Matter) work remarkably well because they run away from the player, exposing their weak side.
• The name of the monster is a reference to the Darknut (also known as Tartnuc) knights from The Legend of Zelda who, similar to The Binding of Isaac, cannot be harmed from their front.

Bugs

Bug! Floating Knights cannot fly over key blocks.

Bug! The hitbox of Dark Red Champion Knights (and their variants) do not change when they crumble into goo, and they must be shot from the back to damage them.

Bug! Knights are briefly invincible during their spawn period.

Bug! If Isaac charms a Knight and it is the only enemy in the room, the Knight will chase Isaac but will not charge, making the Knight more difficult to damage until the effect is gone.
