Got this from the google doc of translations of current ninjas in China floating around the forum:

Mystery: [Prompt] Attack up to 4 enemies, and cause heavy nin-taijutsu damage, knockdown and immobile to the target.

Battlefield Entrance Cooldown: 1 round

Cooldown: 2 rounds

Chakra Consumption: 60

Standard: Attack the enemy, with a certain probability of causing high float

Chase: Triggered by a 30-hit combo. Hits 2 enemies, and disperses all buffs and shields, as well as poisons the targets.

Passive 1: Before the first action of each round, damage a random team member, and reduce the cooldown of this ninja’s mystery by 1.

Passive 2: If this ninja is killed, it resurrects with 30% health after 2 rounds.
