Really loving playing my unarmed Berserker character, and picked up Tavern Brawler in order to improve the experience, but I cant help but feel without multiclassing into Monk, unarmed isnt viable for other classes as a main focus.
I think there needs to be a few improvements to Unarmed, Improvised Weapons and Thrown objects to ensure it can keep up with other playstyles, and be accessible and rewarding for other classes besides Monk, but without making Monk less appealing.
So with that in mind, I would like to suggest a few changes that I feel would be welcome additions to the game and do not deviate too much from the 5e system its based off.
Unarmed Strike: Characters without any weapons can only make a simple Unarmed Strike. However, I feel as though Unarmed Strike should also be available to anyone without an offhand weapon or shield.
Unarmed Slam: Characters with no weapons or shield should be able to perform an Unarmed Slam. Unarmed Slam deals more damage and can potentially knock a target prone.
Unarmed Proficiency: Monks, and anyone with the Tavern Brawler Feat, should have "Unarmed Proficiency", allowing them to make weapon attacks with unarmed and changes unarmed damage from 1 to 1d4.
Deft Strikes: With the above changes, Deft Strikes will be changed so it allows you to add your Dexterity Modifier as normal, but does not increase damage.
Unarmed Fighting: Add this fighting style to Fighters, Rangers and Paladins. This adds Unarmed Proficiency to the character, and when fighting without a shield or weapon you can make an unarmed strike as a bonus action.
Archery: This should apply to weapons with the Thrown quality (but only when thrown, obviously).
Grappler: Add this feat from 5e. Grappler allows you to pick up Medium Creatures with the Throw and Improvised Weapon actions.
Grappling Strike: Add this manoeuvre from 5e. Grappling Strike adds your manoeuvre dice to damage and attack rolls when using the Throw or Improvised Weapon actions on Creatures.
