Bomber Boy

Bomber Boy is a passive item added in Afterbirth.

Effects

 * Grants 5 bombs.
 * Causes bombs to explode in a large cross-shaped blast by adding two additional explosions in each cardinal direction.
 * The damage for a single explosion is unchanged, but each successive explosion that hits the same enemy has its damage halved; for example, if 5 of the explosions hit the same enemy, the total damage is 60 + 30 + 15 + 7.5 + 3.75 = 116.25 instead of 60 * 5 = 300.
 * changes the base damage to 110, with the same halving reductions as above.

Synergies

 * : Spawned bombs explode in a cross pattern, therefore covering a wider area.
 * : The range for poisoning nearby enemies is much bigger.
 * /: Each explosion counts as an individual Butt Bomb, so this deals 90 damage per explosion to all enemies in the room.
 * : The troll bombs spawned by the effect of this item will explode in a large cross pattern, making them more likely to damage both enemies and Isaac.
 * : Bomber Boy also affects the bombs fired by Dr. Fetus.
 * : Each explosion has a independent chance of generating a pickup to use.
 * : Creates fire in a shape of a cross.
 * : All explosions deal more damage, have a larger radius and will overlap each other more, potentially vastly increasing damage.
 * : Each bomb can restore multiple red hearts.
 * : Each of the nine explosions will have its own tear burst.
 * : Each of the smaller bombs explode in large cross-shaped blasts.

Interactions

 * : Epic Fetus explosions are unaffected.
 * //: Explosion damage is halved with no additional explosions.
 * : Ipecac explosions are unaffected.

Trivia

 * Bomber Boy is a reference to the 1983 video-game Bomberman.
