Bah on this whole character pregnancy negativity. Life has given you a beholder and you're thinking "Oh crap, here is a monster with multiple attacks that could kill or incapacitate me with anyone of them." instead of "Think of all the money I'll make once this thing is dead and Bender is making beer out of it."

Depending on how mystically protected the pregnancy is (if it is at all), you could lobby for part of the little mutant's Natural AC and DR.

Besides Wah-Keen (yes, I probably mispelled that) might consider a Half-Titan from one of her clerics to be a good investment. and you know how Wah-Keen is about investments.

And if you do carry to term, by my calculation it'll be time for the Dragonborn's gift giving celebration/storytime thing that The Monster was all ga-ga for shortly there after.

I'll start with the hiding now.
