Different items

i see that there are rare items, special items, relics items and etc..
what does all these items do? apart from being able to be use by the chars~

another question, the game mode easy, normal, hard.. does it have any big difference?

The items give the characters special bonus or stats enhancement. SOmetimes they are useful for quests too.

Easy means less enemies and more save points.

Hard gives no speacial reward, just less ssave points and more enemies.

I think that's it, at least

thanks alot firefly

Also,keep in mind that the Easy mode doesn't give you the game ending,it ends a while before that.
