Slayer

An experienced adventurer who only concerns themselves with hunting one particular creature type to the point of extinction, you work in studying the habits and biology of your prey. The jobs he takes only involve goblins and he takes no others, though he often gets roped into more dire quests for reasons beyond his control. Your style of combat relies more on pragmatism such as setting traps, using a weapon against its user, and taking whatever advantage that may come. You use your imagination to re-purpose defensive abilities to kill your prey. Your most defining trait is your ability to slay your prey. Whether your motivation is revenge, tradition, or boredom.

Favored Enemy

Beginning at 3rd level, you have significant experience studying, tracking, hunting, and even slaying a certain type of enemy.

Choose a type of favored enemy: aberrations, beasts, celestials, constructs, dragons, elementals, fey, fiends, giants, monstrosities, oozes, plants, undead, or a humanoid (such as gnolls or orcs) as a favored enemy.

You have advantage on Wisdom (Survival) checks to track your favored enemy, as well as on Intelligence checks to recall information about them.

When you gain this feature, you also learn one language of your choice that is spoken by your favored enemies, if they speak one at all.

Whenever you make a melee weapon attack using Strength against your favored enemy, you gain a 1d6 bonus to the damage roll that increases as you gain levels as a fighter. The damage increases by 1d6 at 9th and 14th level.
