Why Gift of Reason?

[Vger]

Hi,

OK, I'm playing R'lyeh and just had a Vastness show up at the Void Gate. I gave him (it?) Gift of Reason. Now, I did get research of 6 and Astral 3 out of that, but he can't carry anything, even misc, so am I missing something? I don't see a big benefit of having done that.

I do realize he can command troops and also that there may be several marvelous Astral spells he can cast before attacking, but I expected something more.

So, in short: Why use gift of reason?

Thanks,
V'ger gone
