Quick background on character concept before I get to my question. Formicus is a young Tremere Terram specialist with a fascination for ants. During his apprenticeship he kept an ant colony which he diligently cared for, including occassionally using vis remnants and other lab refuse to augment the ants diet in the hopes that something strange and magical might happen. One of the soldier ants did become magical and intelligent and starts the game as Formicus's magical animal companion he calls Caesar.
The minor story hook being Formicus investigating the organizational structure of the ant colony and attempting to reorganize the hierarchy to put his friend Caesar in charge of the ants. Of course Formicus will use magic to talk with the ants, mutate the ants and cause all sorts of follow on stories revolving around Caesar and Formicus's ant obsession.
Formicus will also eventually make Caesar his familiar so that Caesar doesn't die of old age after only a few years of game play.
So with that background in mind, I am trying to design Caesar the Ant and I am looking for input.
Here is what I have so far:
A mouse is size -10. The average mouse has a mass of approximately 30 grams while the average ant has a mass of 3 milligrams which means it takes approximately 10,000 ants to equal the size of a mouse. According to the rules each factor of 10 is equivalent to 3 size therefore Caesar has a size of -22.
As a magical companion, Caesar's magic might and intelligence is based upon his size. His magic might is obviously 32 while a size difference of 5 seems to equate to about 3 points of Intelligence roughly so his Intelligence becomes 10 (magic creatures are not limited to the +/-5 scale of humans).
It is likely that Formicus will use magic to make Caesar human size. Using the rules on Modifying Beast Sizes in the Mundane Bestiary, Quickness and Strength will be modified according to size changes. A human-sized ant should be equivalent to a normal human in terms of Quickness and stronger than any human (ants are noted for being exceptionally strong for their size) so with a target of Quickness 0 and Strength +6 at Size 0, the Size -22 numbers become Quickness +22 and Strength -38.
This is what I ended up with on my first draft:
Magic Might 32 (Terram)
Characteristics: Int +10, Per +2, Pre 0, Com +3, Str -38, Sta 0 Dex -3 Qik +22
Confidence Score:1 (3)
Virtues and Flaws: None
Personality Traits: Loyal +3, Hard Working +3, organized +3
Bite:Init +22, Attack -3, Defense +22, Damage -38
Fatigue Levels:OK, -1, -3,-5, Unconscious
Wound Penalties: -1 (1), -3 (2), -5 (3), Incapacitated (4), Dead (5+)
Any obvious mistakes or ideas on how to refine the mighty Caesar?
