Witcher Expertise

All Witchers are different. For their specialty prey - some have keener senses. Some spent more time in research. Others spent more time in combat training. Choose 1 of the 3 below: (Manticores get to choose 2 in exchange for losing the 'Favored Enemies' trait)

Tracker

A Witcher goes unpaid if they fail to find their prey. When tracking creatures of your specialty, you are considered trained in the Survival skill. If you are already trained, you gain expertise. If you already have expertise, you gain advantage.

Loremaster

An unprepared Witcher is a dead one. Witchers may recall creature strengths, weaknesses, and other special traits. When attempting to identify creatures from evidence, you become trained in the Investigation skill (If you encounter the creature without yet identifying it, you may roll with disadvantage). If you are already trained, you gain expertise. If you already have expertise, you gain advantage.

Slayer

If a Witcher can't capitalize on their prey's weakness, they'll create one. When fighting creatures of your specialty, you may add your secondary stat bonus to either your attack rolls or your damage rolls, which is chosen on initiative. The bonus is applied to only one attack per turn.
