Hero to the people of Salny, infuriating pest to the Imperial Command. A monster born on Salny Island, from all the prayers of the people, Dianto is entirely unique. Salny Island is a land locked in a war with Gigante, whom he is willing to fight alone if necessary. Despite his origins, Dianto is able to speak the common language of people.
Dianto is a tank and fairly good support character, usually outclassing someone like Kanata. Because of his high HP, Scarecrow can be used as a last resort to protect the others, although you want to be careful around enemies with party-wide attacks. Courage is great because you will be able to withstand a fatal attack, so use this when you know Dianto is going to fall in battle. Steadfast is a great buff that improves both the party’s physical defense and their magical defense. To improve on his support role, Asgard is a great skill to use when you need other allies’ skills to come back into play, while Invisible will help in making the party survive.
As far as his attacks go, the few he has, they have some area of effect and either hit multiple times or have some kind of debuff on them. Rumble will hit all enemies once, Tornado will hit four times within a fairly decent range, and Zero Force hits all enemies while inflicting Physical Mar. Overall, Dianto is a great addition to the team and definitely a useful character towards the end of the game.
