Q186a: can a Changeling with Racial Emulation qualify for the Beholder Mage PrC if he takes the form of an Medium-size Incarnate Construct Half-Golem Beholder, since it would be a humanoid?
A 186a
No, Minor Change Shape is based on Disguise Self, which is a lot more lenient-- you don't necessarily even have to look like something that exists. However, there's the question of whether... whatever that thing is actually counts as a "True Beholder". (I imagine most Beholders would say not.) There's also the question of whether it has the same "body type" as a changeling-- in this case, two legs, a torso, a head, and some number of pairs of arms. (I'm not familiar with all those templates, but I'm guessing not.)

Q169
How can I (as a psion shaper/constructor) make my astral constructs overcome damage reduction? Such as alignment based, cold iron, silver, epic, magic, and adamantite?
A169: I don't think there's a way to make their natural weapons overcome DR, but there are a couple of menu options that let your constructs manifest psi-like abilities, such as Concussion Blast, and one that causes their natural weapons to do energy damage. Those would ignore DR.
