Added in Repentance

Rocket in a Jar is a passive item added in The Binding of Isaac: Repentance.

Effects[edit | edit source]

  • Adds 5 bombs.
  • If Isaac is currently moving or shooting, placing a bomb will instead shoot a fast-moving, explosive rocket in the direction he's facing. Otherwise he will place a regular bomb.

Notes[edit | edit source]

  • Rockets use Isaac's bomb synergies like his bombs normally would.
  • Rockets are unaffected by Isaac's shot speed.
  • Rockets can be pushed back by 15►Brimstone Brimstone lasers.

Synergies[edit | edit source]

  • 15►Dr. Fetus Dr. Fetus: Shoots rockets as normal tears. All synergies that would normally apply are given to the rockets.
  • 15►Bobby-Bomb Bobby-Bomb: Rockets become homing.
  • 15►Marked Marked: Rockets can be controlled like tears.
  • Giga Bombs: Fires a giant rocket that moves slower and has the same effects as a normal Giga Bomb.
