Hi, the boost to attack when bb gauge is full only applies to normal attack not with using bb/sbb, with oguro's unli sbb, that gives him boost to attack automatically due to his ES. Same goes when divine gem is equipped.

When your bb gauge isnt full and you have a sphere/LS that boost bb gauge while attacking, the time when youre bb gauge is filled, thats when the attack boost applies when using only normal attack.
