Base Class: Barbarian
The Brewmaster's life revolves around their love of making and drinking beers; they even incorporate beer drinking into their fighting style. A true Brewmaster will strive to cleave his enemies fast and drink a beer over their still hot corpse. The Brewmaster balances offense and defense to make sure his side is on the winning end of any battle.
Tools of the Trade
Upon taking the Path of the Brewmaster you must craft your own Brewmaster's Tankard. The Brewmaster's Tankard is extremely important to a Brewmaster and must be made well and taken care of. The Brewmaster can choose the style and appearance of their tankard.
Additionally you become proficient with Brewer's Supplies.
Drunken Fury
Starting when you choose this path at 3rd level, you go into a drunken fury when you rage. For the duration of your rage you can drink from your brewmaster's tankard as a bonus action on each of your turns. When you do this you can make a single weapon attack using your tankard as part of that bonus action. The damage of the tankard is 1d6 + STR Modifier bludgeoning damage and you are proficient with your tankard.
Comfortably Numb
Beginning at 6th level, you gain the ability to ignore pain while drinking. After you drink from your brewmaster's tankard using the drunken fury feature, you may use your reaction to reduce the damage from an attack on yourself by 2d6.
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.
Drunken Revelry
Beginning at 10th level, you can use your action to bolster your allies with your drunken spirit. When you do so, choose up to five friendly creatures that can see or hear you, and bellow a drinking song to them. The creatures you chose gain temporary HP equal to your CHA modifier + your barbarian level.
Once you use this feature, you can't use it again until you finish a long rest.
Ice Cold Brew
Starting at 14th level, your brewmaster's tankard is always magically cold. Your brewmaster's tankard now strikes with cold damage and uses a d10 for it's damage die.
