MB is an acronym for Magic Burst. Specific to FFXI, a Magic Burst occurs when a mage fires off a spell in co-ordination with a combo executed by bashers and damage dealers. In order to be sucessful and Magic burst must employ a spell of a type matching the combo being performed by the other members of the party. It is possible to have more than one mage complete a magic burst per combo.
