Chronicle of Legends is out and there is a capstone for the magus. I think it's name is Legendary Blade. Someone know what it does?
Additional +2 enhancement bonus (total +7) when he enhances his blade from his arcane pool.
Wait...some people get their characters to 20?
17's my limit so far, but there's at least one or two APs that go all the way.
We managed it in one campaign, but our GM put us in a "fast forward" mode where we gained a level per session near the end of the campaign. I have never reached levels in the teens at a normal pace.
There are people who play L20 one-shots or arenas. There are people who say 'Yeah, yeah, we always play from 1 to 20' - I'm not sure I believe them, especially since I've noticed a couple of them coming back for new character builds faster than is likely with that.
I've had characters reach 18 on the "medium" xp track over the course of a very long campaign that I ran.
