Casting Sleep or Night is effective as Bombs are not immune to Sleep status and sleeping Bombs can be attacked with non-physical skills. Attacking with Wind, Ice, or Water-elemental weapons or skills can help as Bombs are weak to all three, but one should avoid using Fire-elemental attacks as Bombs absorb them. It is recommended for Quina to try and Eat a Bomb early on to learn the valuable Mustard Bomb spell.
If the eidolon, Fenrir's Terrestrial Rage attack is summoned on Bombs, sometimes when they use Grow, their graphic will disappear and they become invisible. If the player then inflicts them with Poison or Darkness, only the status effect's graphics float in the air.
