Character

Can i change my character ? There are changes in villages and my hero will not be like i think

I'm assuming by character you mean this. Yes you can change your character/hero if you feel the need to. And it's not necessary that you have to update it on the forum as there's no rule as such for that.
Also it would've been better if you'd have asked this on the shoutbox instead of making a post about it. I'm sure someone would've answered. Anyways I hope I've answered your question.

What you can do is go back to your post about your OC and simply edit/modify your post and change whatever you want. You can change your OC as many times as you want.
