I was wondering if a character is limited to the number of Talents as listed on the "talent pyramid" in the back of the book. Can anyone clarify this? It would make sense in a way if that is the case, because it will mean that the player is forced to take into consideration that there is a limit to the number of talents that he can invest in his character and make some tough choices along the way.

Or do you simply just keep adding more rows underneath the last line on the "talent pyramid" with talents from Tier 1 through Tier 5? And thus effectively letting every character potentially get all Talents once enough experience has been accumulated and spent...

No limit is mentioned anywhere in the text, so my assumption has been that you simply continue on after filling that page.

I'm with buxton here; the book doesn't say there is a limit and instead just states that you simply must have more rank 1 talents than rank 2, more rank 2 talents than rank 3, etc. And all of that is handled by the top of the talent pyramid.

Note, since you can keep buying ranked talents past rank 5 as further rank 5 talents, there isn't really a notion of "all" talents, but rather some point where you run out of rank 1-4 talents. Really the choice is in how to best spend xp.
