Whats the point in doing the bonus in missions??

After, you have reached level 20, is there any other reward than exp? or any other reason to do them? I'm going to get them all because they are fun but isn't exp useless now?

thanks

Ok, a couple of things actually...

1, skill points
2, experience giving you more skill points
3, some give gold as a reward aswell
4, getting all the bonuses on the chapters gives you the "Protector of..." title for that chapter

If you have not done the bonus, then the mission completion does not count towards the Protector title.

Experience after level 20 gives you skill points for purchasing additional skills.

Protector title mainly.

And if you're a lowlevel they boost u slightly in terms of exp
