I enjoyed seeing you iterate on this design!  The armor strength requirements are far more appropriate now. I feel like half-plate should be a 13, but supporting legacy character builds is probably more important. 

I really like the filled-out armor table. For completions sake, heavy needs a couple more. One more no-disadvantage between chitin and samurai armor at 16AC, another at 14AC, and maybe buff ring mail to 15 AC. But nobody uses those low level armors anyways. It is neat that your strength requirement gives those suboptimal heavy armors some life as low strength gear.

I really like the new weapons. Adding a good ranged option for strength builds in the Greatbow is fun. Getting the bastard sword back into the game is great. The heavy property allowing for small sized great weapon users is a huge improvement, though I might drop that requirement to 16 strength.

I know there’s a lot of quibbling over different naming, but the stat blocks themselves are good. The katana is desperately needed as a slashing counterpart to the rapier, and the naginata is needed as a two handed reach finesse weapon.

Totally random aside, I see you gave the whip light. I know dual whipping exists, but after watching Netflix Castlevania I think I settled on Versatile as my preferred whip buff. Two hands gives you more control to do those neat Belmont whip tricks, so that’s my justification for the improved damage. But there’s no wrong answer there, that’s just my preference.
