Bituitus

Bituitus is a enemy in Final Fantasy XIII. It is the mark of Cie'th stone mission 7: Bituitus, the Pillager

Strategy
Since Bituitus halves all elemental damage and is weak to magic it is wise to use non-elemental magical abilities. Like Ruin or Ruinga so bring your 3 Commandos to the field and just blast away until it dies. Secondary could be (COM+COM+SYN) so when commandos attacks synergist buffs the party f.e. Haste is recommended
