Notes

  • The Bracket Key can hit bosses such as Cannonbalrog and High Priest during attacks where they are normally invincible.
  • The explosion cannot travel to other rooms (e.g. using the item in a room adjacent to a chest room containing a Mimic will not damage it).
  • Unlike [Big BoyBig Boy] , the damage done by Bracket Key will not contribute to its own recharge.

Trivia

  • The Bracket Key's tagline, description, and functionality suggests that the right bracket key on the keyboard was used during development of Enter the Gungeon to automatically clear rooms for debugging purposes.
  • The synergy Square Brace is a reference to the character Curly Brace from the game Cave Story, where the gun [PolarisPolaris] is also from.
