I was wondering if if ther is any added benifit for going past 10 lvlv in any prestige class? Looking at the arcane archer it show all the benifits up to lvl 10, but are there any added benifits after lvl 10?
Thanks for any and all inforamtion.

For most of them, yes. The AA's enchant arrow feat improves by 1 every 2 lvls past lvl 9, for example. I'm fairly sure the manual has a listing for each classes epic benefits.

You should be able to garner more info here, about specific prestige classes you have in mind.

Thanks for the link! I learned alot there

No problem.
