Mustard Bomb is an ability that appears in the Final Fantasy series as well as in Dragon Quest Tact. In Tact, it is one of Omega's signature skills, launching an explosive filled with mustard gas at an enemy. The chemical agents in the gas can also render the target paralyzed.
Mustard Bomb is known naturally by Omega at level 1 and costs 44 MP to use. It has a range of two to four squares away from it in any direction and inflicts moderate martial damage to a single enemy and can occasionally paralyze them too.
