Hello everyone. To start, I'll supply the author website here such that everyone can potentially purchase the books if they are interested in the series. I'd highly recommend it. I'm personally not normally into romance novels, but this paranormal romance trilogy was really well written, with such fantastic character development that it was hard for me to put down.
Were-Cats[]
Compliments aside, getting into the statistics of the verse. The powered characters of the verse come in the form of preternaturals, the most prominent of them being witches and were-cats. Were-cats are capable of turning into cats, and have strength to casually snap human bones in half. Using The Real World page statistics would help greatly with the verse, as they literally turn into whatever their cat spirit is. Whether it be a lion, cheetah, leopard, or something different, as there are those in verse capable of changing into things other than cats as one might suspect. For the most part, the cats in their cat forms would be from 9-C to 9-B depending on their cat, paired with Superhuman speed. However, I am not sure what tier their regular, human form would be, for they still retrain a good portion of strength from their full cat state. Enough that, as mentioned earlier, they could kill a man merely be snapping his collar bone, shatter the bones in his hand by shaking it, or outright killing him with a well placed blow.
Witches[]
As for witches, most of them are a decent chunk above average when it comes to physical characteristics, being able to take more blows than the average man, and even run faster, in addition to having a better immune system, though not as good as their were-cat counterparts. I'd assume most of them would be in the 10-B to 10-A range physically, with Athletic Human as their speed tiering. Though, with magic, they are capable of harming even werecats, such that even a mid tier with would likely be 9-C with magic, and higher tier witches 9-B with magic. It should also be note that witches are given a strength level from 1 through 5, which is important for scaling. 1 is the weakest, and 5 is the strongest.
I will provide evidence for calculations as needed but I believe that this should at least be sufficient for preliminary statistics for the verse.
