The Spritz Bomb is a powerful explosive, and is usually the highest level Explosive-type weapon. It is a bomb that, upon impact, releases many smaller bombs. Like most ranged weapons, the ammo is unlimited. Anthony uses a set.
Although it may not look that strong, its power is in its multiple attacks. So while it may have half the attack power of the Second-best weapon, it attacks five times (doing over twice the damage). It occasionally has a fire-based attack.
Sometimes, it is also a special ability of an enemy.
