Synergies[]

  • 15►Dr. Fetus Dr. Fetus: Bomber Boy affects the bombs fired by Dr. Fetus.
  • Added in Repentance15►Epic Fetus Epic Fetus: Bomber Boy affects the missiles' explosions from Epic Fetus, with the explosions' multiplier resulting in 15 times Isaac's damage per explosion. Unlike with regular bombs, Bomber Boy won't decrease the damage from each of the missile's successive explosions, drastically increasing damage.
  • 15►Mr. Mega Mr. Mega: All explosions deal more damage, have a larger radius and will overlap each other more, potentially vastly increasing damage. Caution should be exercised, as the explosions' increased radius make self-damage likely.
