Yea Isterio is used to apply ailments (sickness, parayzle and curse) to prevent the bosses and sub bosses from doing ultimate attacks. Bonnie is great sub, only thing you might have to worry about is Bonnie's ubb doesn't have a 100% chance to inflict status ailments (like Isterio's ubb does), so you might have to pray that RNG is on your side when trying to avoid ultimate attacks.
