Triachnid is a boss that can appear:

Behavior[edit | edit source]

Triachnid's head hangs down stationary and can perform the following attacks:

  • Raises his head and stomps the ground in random locations around the room 3 times in quick succession, leaving small puddles of slowing White Creep.
    • His head cannot be damaged until lowered after the attack.
    • The appendages that he stomps with can be attacked to damage him.
  • Lifts his head off-screen and stomps the ground 3 times at regular intervals on top of Isaac's position. At the end of the stomps, he slams his head down quickly in the center, center-left or center-right (whichever is closer to Isaac's position), shooting 8 white projectiles in all directions and creating a large puddle of White Creep.
    • Occasionally performs a fourth stomp before slamming his head down.
    • Occasionally, when he slams his head down, he leaves a larger puddle of White Creep, but only shoots 4 white projectiles in the cardinal directions.
    • The appendages that he stomps with can be attacked to damage him.
  • Spits out a Trite in Isaac's direction.

Notes[edit | edit source]

  • Added in Repentance Triachnid no longer spawns in The Womb.
  • Added in Repentance Unlike all other other alternative versions of bosses such as Dangle, C.H.A.D, and Gish, Triachnid has the same weight as his alternative boss form.
    • Although they share the same weight, Triachnid is actually more common than Daddy Long Legs, since he also appears in Scarred Womb.

Trivia[edit | edit source]

  • Triachnid was added in the Wrath of the Lamb DLC for the original The Binding of Isaac.
    • IN the original Binding of Isaac, Triacnid could be encountered in Necropolis Necropolis.
  • Triachnid originated from the 2006 flash game Tri-achnid, which was created by Edmund McMillen.
  • He is an alternative of Daddy Long Legs.
  • While Daddy Long Legs uses 4 appendages in his attacks, Triachnid is reduced to mostly only using 3; this is most likely in homage to the fact that Triachnid in his title game only had 3 appendages.
  • Triachnid's unlock method is possibly a reference to a bug in the original Wrath of the Lamb that caused Triachnid to occasionally replace Isaac in the Cathedral.
  • Removed in Afterbirth † Triachnid does not have a death animation.
  • Added in Afterbirth † Triachnid can be found in The Void The Void, even before being unlocked.
