Proposal: The Thing in the Basement, Take 2

I see Kevan's point about the last monster in the basement, so here's a new version:
If "Proposal: I'm not mad! Just a little angry" passes, create a new rule:

One of the Doctor's experiments lives in the basement and needs to be fed. At intervals of no longer than eight days, the Doctor should choose a specimen at random from a list of specimens that are not dead, but can be undead. The Doctor can include himself on this list, but is not required to do so.

The specimen chosen from the list must make a nice meal for the monster in the form of 4 life force, or the amount of life force remaining in that specimen, whichever is closer to zero. The Specimen who fed it will then receive from the Creature a single biological modification (no Abs of Steel) increasing his or her lowest Attribute by one. This modification can raise a Specimen's Attributes above the ordinary maximum limit. If two or more Attributes are tied as the lowest, the Doctor should randomly choose one Attribute to raise.

If the Doctor neglects to choose someone to feed the creature, it attacks him at a cost of 20 life force and does not modify him at all. (It likes him just the way he is.)

The name of this rule is the name of the creature, affectionately chosen by the Doctor many years ago. If the Doctor does not choose a name, it defaults to "Carol."
