Path of the Drunkard

For some men, the taste of alcohol can draw them into a ferocious stupor, harming those around them with no concern for those around them. The only gifts they are given in their lives are a strong liver, and a strong body, which they take advantage of.

This subclass takes ideas from a few sources that I'm unable to link because of dndbeyond rules. A big part of which is from the blackbando's path of intoxication.
I used various parts to fit the idea I had in my head

One too many

Bar fights are part and parcel of a good night, you've become adept at wielding whatever ends up in your hands. Whether it be a tankard, stool leg or passing goblin.

You gain proficiency in improvised weapons

Drink

Due to many nights of nothing but grain alcohol, your body has adapted to wrestle any nutrition out of your brews.

Starting when you choose this path at 3rd level, while raging you can take a swig of your brew as a bonus action, invigorating you. When you drink you gain 2d4 temporary hit points, you can do this as many times as equal to your CON modifier +1 (minimum of 1)

When you deal damage with an attack you can add any remaining temporary hit points from this feature onto your damage, doing so uses them up

The die increases to 2d6 at level 6, 2d8 at level 10, 2d10 at level 14 and 2d12 at level 20

Comfortably Numb

Beginning at 6th level, you gain the ability to ignore pain while drinking. While raging you may use your reaction to reduce the damage from an attack on yourself by 2d6. You can do this a number of times equal to your constitution modifier +1 (minimum of 1)

When you reach certain levels in this class, you can reduce the damage by more: by 3d6 at 10th level and by 4d6 at 14th level.

Swerving

Your stumbling movements have become hard to predict, on your turn if you haven't already moved you can choose to half your movement for that turn but enemies cannot take attacks of opportunity against you.

Rabble Rouser

By 10th level, the towns and cities of the world are all like home to you. Carousing, drinking, and partying all count as light activity for the purpose of resting for you.

In addition to that, you become instinctively aware of what's around you when drunk. You gain a blindsight of 5ft when raging
Your drunken movements also become too unpredictable for enemies to make advantage of, while raging enemies do not get advantage for pack tactics or flanking.

Wild Swings

At 14th level, your attacks are more potent and random than they would normally be. While you are raging and hit a creature with a melee weapon attack, you can choose for that attack to be a critical hit. You get one free use of this feature per long rest, using this feature afterwards gives you a point of exhaustion, which you receive all at once when your rage ends.

This does not count as rolling a 20 (Sorry vorpal sword users)

You also do not suffer the effects of exhaustion while raging, if you gain any other source of exhaustion points while raging, apply them at the end of your rage. If you have 6 points at the end of your rage you die as per normal.
