Runk chooses the Path of the Berserker. When he rages, he can choose to enter a frenzy. If he does, he can make one melee weapon attack as a bonus action on each of his turns after the turn he entered the frenzy. When the rage ends, he suffers one level of exhaustion.

Runk can enter a rage three times between long rests. While raging, he has advantage on Strength checks and Strength saving throws, gains a +2 bonus to melee damage rolls using Strength, and has resistance to bludgeoning, piercing, and slashing damage. Rage lasts up to 1 minute, ending early if he is knocked unconscious or if his turn ends without having attacked a hostile creature or taken damage since his previous turn. He cannot cast or concentrate on spells while raging.

While not wearing armor, Runk's Armor Class equals 10 + his Dexterity modifier + his Constitution modifier. He can use a shield and still gain this benefit.

On his turn, Runk can attack recklessly, gaining advantage on melee weapon attack rolls using Strength during that turn. Until his next turn, attack rolls against him have advantage.

Runk has advantage on Dexterity saving throws against effects he can see, such as traps and spells. He does not gain this benefit while blinded, deafened, or incapacitated.

Runk retains the respect of soldiers who recognize his former service. He can find shelter and assistance among friendly military forces, though he cannot automatically call on them for dangerous or costly aid.
