A witcher -- also known as a wiccan, hexer, vedymin, or witchman (Elder Speech: vatt'ghern), is someone who has undergone extensive training, ruthless mental and physical conditioning, and mysterious rituals in preparation for becoming an itinerant monster slayer for hire. Witchers of the School of the Bear rely on heavy armor to protect them and use heavy strikes to bring down their foes.

Though they cover proficiency in basically any weapon that comes to hand, a witcher's training focuses on two primary tools: a sword of steel, and a sword of silver. These swords are typically carried on the back. A steel blade used for more mundane beings, while a silver blade for beasts of the supernatural. Witchers are also frequent mixers and users of powerful potions, having developed an advanced tolerance to their inherent toxicity, but still limited to a few at a time (even one of their weaker brews would be fatal to an ordinary human). Finally, their formal magical training deals with signs, a low-level yet versatile form of magic that allows witchers to cast spells and enchantments with simple hand gestures. Without extensive improvement and practice, these are mere tricks compared to what a sorceress can do, but they serve very well for someone with a sword in one hand to add a variety of improvisation to their efforts. Also, the more powerful magic used by mages often takes a lot of time to prepare while all signs are instantaneous. Additionally, witchers are trained by seasoned mages in how to use these signs to the best effect.

In general, a witcher is a formidable and often overwhelming opponent to more mundane races thanks to their superhuman physical prowess, regenerative capabilities, and magic. However, they are not infallible, as they can still make mistakes, take a misstep in battle against mundane men or supernatural demons, or be overwhelmed by sheer numbers and individuals who have the skill to match a witcher, though rare is the individual who managed to slay a witcher out of skill rather than dumb luck or by ambush.

You must finish a short or long rest before you can use this ability again.
• Magic Sensibilities: Whenever you damage an enemy with one of your signs roll a d20. On a 20 you critically hit the enemy, allowing you to treat the damage as if it where a normal critical hit. This ability doesn't apply if the enemy critically failed a saving throw to avoid the signs damage.
