Passive skills limit?

[xxjoseluisxx]

I was wonder if there was a limit on how many points could be on a passive skill. So is there? And if so what is it?

there is a level req, just like skills. i know at 20 you can have 3 of the attack and 2 of the damage one. idk about the rest other than at 25 you can have 4 of the damage one ;S
