Oh, I'm sure what Farxus is about to do is going to get some attention. If it's good or bad is debatable.
Just a quick reminder; If I wanted to create a race of supernatural creatures with strange eating habits/hunting habits, an aura effect that grows in effect in relation to how many creatures are present (which is proportionate to the amount of food available to them in the area), a somewhat magical ability to preserve the food sources that they can find in stasis for long periods of time and are spirit like in nature (ethereal and able to fly), how much Might would that cost me?
As Vec mentioned, the default cost is 1 Might to create a race of sentient creatures, but nothing is stopping you from investing more.
In my opinion, it would depend on how powerful these abilities are, and how closely it ties in with your Domain/Portfolio, as to whether you should invest extra Might. Strange habits would not affect cost. Preserving things in stasis is an interesting ability, but probably not big enough to affect the cost. Being spirit-like ties in with your Domain/Portfolio. This leaves the aura effect. If the aura effect is especially powerful/dangerous, then it might be worth investing another Might. If the aura effect is not as powerful/dangerous, especially if it is linked to your Domain/Portfolio, then it shouldn't require more Might.
