A150:
No.
With the rare exception of the times where it says it does. And a nice DM would just give it to you...
Could you sight me any of those examples.
it's a matter of simple deduction. Every single thing that grants evasion simply leaves it at that --
never does it say anything like "if you already have evasion, you get improved evasion instead" (and given the nature of an
exception-based rules set, this is important). By contrast/comparison,
uncanny dodge (another class ability that gets improved with higher levels) specifically states such an improvement. Why would they go out of their way to indicate this
every single time with uncanny dodge, and never mention it even once for evasion (unless, of course, you are
not supposed to get that kind of upgrade)?
Just my 2cp.
