Phirra Darnos - Not many, probably about a dozen, but with good evasive capabilties, could probably just run away.
Katherine Nought - If alone, no more than one. If given a few days to prepare (i.e. grow genetic monstrosities in artificial incubators) many hundreds.
Tahzra - Less, more like half a dozen. Essentially a normal human with a big axe.
Emily Karn - Similar amounts (half a dozen). Increases dramatically with even with smaller weapons such as daggers, but does not personally own one.
Natalie Johanna - At most one. Functionally normal human with no weapons.
Rosa Stoneheart - 4 to 5 dozen. Tiredness will win out eventually.
Lanowen Pendragon - Around 2 dozen. Very skilled swordfighter, but no relevant magic, etc.
Isaya Niscent - 3-4 dozen, most takedowns will be nonlethal. Evasion will be easier and probably a better decision.
Paige Davis - Not even one. Only possessed magic will not be fast enough, otherwise a normal human that needs a crutch to walk.
