I like your ideas. I’m at work, and my break isn’t long enough to dive deep on the document, so I’ll just address concepts.
Versatile (finesse): Love it. I love using versatile to add a property instead of adding damage.
Spiked Chain: Yes, good. I’m here for it. I generally just make it a whip with versatile (1d6)
Off-hand: awesome. A much appreciated fix. Great!
Finesse reach weapons: don’t get rid of these. There has to be a different way to avoid dex-PAM. Or do what I do and fix that issue Str side, with prof to damage when you use Str for weapon attacks.
Side note about anachronistic weapons and armor. [shrug]
But seriously, “studded leather” is just leather armor reinforced with metal. There are a dozen different kinds in real life, just assume it’s one of them.
Also, can we add damage dice to shields?
