The devs were cleary afraid this Ryoshu ID would be too strong if she did more damage. Easy aoe, fast speed, high numbers. Her damage is fine, i just wished she had some sort of bleed support with her skills to compensate her double coins.
Also her support passive looks interesting. Since BL faust usually have problems with skill 3 being last, but with haste it will be more likely that she will attack first
Are you talking about the S3 rolling so high? it's thanks to Lucky Pouch it's the Poise Fusion Look it up how to make it it's quite simple and really powerful
