Path of the Slayer

Some barbarians take to their path due to a shameful humiliation they have suffered that leaves them no option but to seek a glorious death in battle. These warriors have but one purpose: to die while fighting the largest, most terrifying foe they can find. Of course, if they manage to survive long enough, they become quite proficient at slaying such monsters instead.

Though this path is most commonly walked by dwarves, whose stalwart sense of honor leaves them particularly susceptible to this fatalistic outlook, others have occasionally embarked upon the path of the Monster Slayer as well. Dwarven Monster Slayers are generally accepting of others who choose the same path—after all, they'll all end up in the same place, eventually.

Troll Slayer

Starting when you choose this path at 3rd level, you become more adept at fighting and killing large monsters. If you are wearing no armor and carrying no shield, you are immune to any charm or fear effects from creatures that are of Large size or greater. Once per turn, if you are raging, when rolling damage against a creature of Large size or greater, you may roll your damage dice twice and choose either result, as long as you are wearing no armor and carrying no shield.

Giant Slayer

At 6th level, the Slayer has become an expert at finding the weak points of the monsters they hunt. If you are raging, your attacks score a critical hit on a roll of 19-20 against any creature of Large size or greater, as long as you are wearing no armor and carrying no shield.

At 15th level, score a critical hit on a roll of 18-20 against any creature of Large size or greater, as long as you are wearing no armor and carrying no shield.

Dragon Slayer

Beginning at 10th level, as a bonus action the Slayer can issue a challenge that forces their foe to meet them in single combat. Choose one creature within 60 feet of you that is of a size larger than yours. If that creature is flying, they proceed 60 feet towards the ground, landing if they reach it. They then move directly towards your character by the shortest possible route, at a speed up to your maximum movement value. If the creature comes within 5 feet of your character, they stop. This movement provokes no opportunity attacks. Only usable if you are wearing no armor and carrying no shield.

God Slayer

Starting at 14th level, the Slayer has survived so many monstrous encounters that they are an expert at bringing down the largest of foes. When raging, and if wearing no armor and carrying no shield, you have advantage on any attack roll against a creature of Large size or bigger. If you already have advantage from any other source, you instead gain a bonus to your attack roll equal to +1 for ever size larger than you the target is.

For example, if you are a Medium creature, you get +1 for attacking a Large creature, +2 for attacking a Huge creature, and +3 for attacking a Gargantuan creature.
