I tried to figure some things out, but its still confusing me.
I know what the three main stats do, but besides that there are a few confusing ones that I don't know the effect of.
The ones that confuse me are Ego and Endurance (the crown and the heart symbol) seen on buff items, Luck (the clover symbol) which is mentioned in the ninja guys tutorial, and Excitement (the flask? symbol).

I've seen Ego mentioned as being the health bar in battle, but that's also what the Endurance stat is? Why are there two stats with the same effect?

Luck is mentioned in the ninja guys tutorial that explains the shop, but nowhere else. Was this stat removed and forgotten in the tutorial or am I missing something?

I have no idea what Excitement does, I can't find it in the tutorials so I don't know what it does... Could anyone tell me?
