For the third Senjutsu, you can add the character Slug Katsuyu, who is the summon of Sannin Lady Tsunade and Sakura Haruno; you could add passive abilities as some percentage of Purify, some percentage of reduced damage in CP and Healing Active Skill.
Hopefully the first pasive effect of snake when character use any skill reduce all skill consumption by 35% and reduce cooldown by 2 turns, using skill can not be dispersed on first use
Just got into the game cuz i remember Ninja Saga from way back; is there a way to give skill points to your element? I remember speccing into wind always lol i cant figure it out here in this game tho
