Rocket in a Jar

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

Effects

 * Adds 5 bombs.
 * If any movement or firing input is given when placing a bomb, a fast-moving, explosive rocket will be shot in the direction corresponding to the input. The firing input has higher priority than the movement input.
 * The rockets accept analog firing input. This means they can be shot diagonally.
 * Isaac will place a regular bomb if no movement or firing input is received.

Synergies

 * : Shoots rockets as normal tears. All synergies that would normally apply are given to the rockets.
 * : Rockets become homing.
 * Giga Bombs: Fires a giant rocket that moves slower and has the same effects as a normal Giga Bomb.

Interactions

 * : No effect.
 * : No effect.
 * Rockets do not explode on impact with surfaces, requiring manual detonation.

 * Worm trinkets: Rocket's trajectory is unaffected.
 * Wiggle Worm + Dr. Fetus: Rocket will wiggle from side to side mid-flight. This is the only worm trinket that affects Rocket in a Jar.
