They r trying to make each main unique without making one glaringly op. Thus the difference.

Fire main has secret jutsu user

Wind main has senjutsu user

Lighting main has anbu style

Water main as medical ninja.

Earth main.. erm erm idk muscles lol?

Also we already have summons as chases.

True do you know how are they going to be activate?

Ehh, for characteristics that need activation/setting it's stated in their talent/skill

For summons, I forgot what lvl it is unlock.

These things r basics though, if your confused better try chatting someone in game or on discord.

no worries.

Secret jutsu user doesnt work well. They should add Sharingan

I care more earth main, they should add "throw a tiny rock" skill to earth main.

It should be op enough to one shot a ninja.

1st mystery actually hits quite hard

all of them should have special skills. im hoping it goes good.
