Bombs

A bomber has to keep Cool when he's got an explosive in his hand, and the Brains to know the right time to throw it.

Bombs shows your ability to wield explosives, ranging through many different kinds, including firecrackers and grenades. Without a high enough bomb skill there are chances that whatever explosive you attempt to use will go off in your hand, or when you least expect it. Bombs are very powerful and are not to be taken lightly, if you have no skill in bombs try grinding using cheap firecrackers or such. Bombs rely on Cool and Brains.
