The document is interesting, but I have a few nitpicks:
- It's true that clubs (and to some extent maces) can be wielded with 2 hands, but those are different (bigger) clubs. I don't think Versatile fits.
- I, admittedly, don't know what a "pistol-club" is (16th century pistols were, honestly, clubs in their own right,) but a pistol should have the "Close" keyword (being able to be shot in melee without disadvantage,) as historically fighting in close quarters was the pistol's whole point.
- Cestus if flavorful, but is basically a gauntlet mode of leather. As such one would expect it to be "Defensive" (your version) instead of "Finesse" (how does one punch with dexterity, exactly?) or at least provide the customary "expend reaction for +1 AC" feature of gauntlets.
I give it 4/5 stars. Hits more than it misses.
