Giving up specilization, and prastige classes

[Azraile]

If you take a wizard variant that makes you give up specilization.

Can you still take a prastige class that appon taking it makes you specilize?

For example could you chose to be a Domain Wizard, and then still take levels in Incantatrix?

[eggynack]

You are perfectly free and clear to do this. There is no specialization prerequisite to entering incantatrix, nor is there anything within the class features that necessitates specialization.

[137beth]

The only special requirement for incantatrix is
Special: The candidate cannot have abjuration as a prohibited school.
If you are a domain wizard, you certainly don't have abjuration as a prohibited school, so all you need are the feat, skill, and casting requirements, all of which are as easy to get as a domain wizard as with a normal wizard.
