From the Chinese description, it is a reverse taunt. So basically only the two teammates will get attacked instead of Odysseus.
I disagree with the assesment you screenshoted, if he indeed get released with the kit above he’s going to be pretty bad, like Maou Nobu-level of bad. The hilarious 20% battery is already reminding me of Maou.
His self-buff is incredibly low at only 1.2*1.2, this kind of buff value is guaranteed to output noodle damage which would need NP buff upon release just to be competitive damage-wise. He doesn’t pack strong enough utilities to compensate for this noodle damage.
The most recent SSR Rider Europa literally has both more charge and more steroids than this dude. Not to mention the whole existing pack of AOE Riders are all damn strong in their own ways, if this man gets released with the kit datamined he will be the Arthur of Riders…on second thought he placement among Riders will be worse than pre-buff Arthur among Sabers.
