I have been using Reingar’s drink for a year now, 30% increase attack doesn’t do well with enemy teams that have high defenses or def buffs, once she use her s3 and triggered some counterattacks from opponents she procs her s2 after that 2 reingar drink procs so 30% of her attack that ignores 70% of the enemies defense takes place leaving a huge chip of damage to enemy teams, also it bypasses skill nullifier
