A Ninja's mudra abilities, Ten, Chi, and Jin, are what makes a Ninja stand out. By chaining the mudra in different orders, the Ninja can choose between various options for their attacks. Of those options, they can choose between area-of-effect attacks, such as Katon and Doton, buffs to theirselves, such as Huton, and straight attacks at various ranges, such as Raiton and Fuma Shuriken.
Trick Attack is a Ninja's main tool for their burst damage, increasing the damage they deal to a target by 10%. While it can only be executed while a Ninja is Hidden, a skill that is not practical in most combat scenarios, the mudra ability Suiton allows for Trick Attack to be executed without the need to use Hide.
Fleeting Raiju, followed by Forked Raiju and Raiton, is a Ninja's most powerful attack. While Forked Raiju and Raiton can be executed from range, Fleeting Raiju requires the Ninja to be in close combat. Additionally, the Ninja's Ninki Gauge is increased when using Forked Raiju and Fleeting Raiju, a resource that is spent on special ninjutsu abilities like Hellfrog Medium or Bhavacakra.
