Monster Hits -- I used the following formula (which brings up the fact that I do need to fix it...):
(Con stat * 2) + (level *(Con Stat Bonus + 5))
However, I need to adjust this so that it is as follows:
Con stat + 20 + (level *(Con Stat Bonus + 3))
This will reduce the number of hits that most creatures have (a few will increase hits).
Also, the Grimalkin should have an AB of 9 (it used to be 7 before I made the last correction, so that is essentially a "putting in the 9 without removing the 7" typo).
ARs were done by feel. Basically, I compared how tough I thought that their skin would be (compared to armor) and gave them that as their AR. Sentient beings, you will notice, have ARs determined by their actual armor worn .
