  • Pickups, chests, and other movable objects will be flung away if caught in a bomb's explosion radius. Take care not to launch anything you want over spikes or other hazards.
  • Troll bombs of all sizes (whether room reward or spawning from monsters) deal a full heart of damage under normal conditions.
  • Added in Afterbirth Troll Bombs explode after a random amount of time. This means that if two Troll Bombs spawn at the same time right next to each other, there's a high chance one Troll Bomb will blow up before the other, sending that Troll Bomb sliding outwards a bit before exploding.
  • Giga bomb explosions will never destroy tiles in front of room exits.
  • The HUD icon for bombs changes to a bigger one when Isaac holds a Giga bomb.
  • Picked up Giga bombs are always used before normal bombs.
  • Picked up Giga bombs will override the Golden bomb effect until all Giga bombs are used and they do not stack with it.
  • The probabilities in the table refer to the kind of bomb that is generated by the game when a bomb pickup is spawned with a sub-type of 0 (i.e. a random bomb).
