Witcher training is extremely selective, physically brutal, and mentally demanding. Candidates begin by mastering multiple weapons, hand-to-hand combat, endurance conditioning, survival skills, monster lore, and basic battlefield magic known as Signs. This training prepares them for the dangerous contract work that defines the profession.
Witchers undergo the Trial of the Grasses, a mutagenic process with a survival rate of roughly 30%. Those who endure gain enhanced strength and speed, superior reflexes, night vision, resistance to toxins, and slowed ageing. These traits, combined with years of specialised combat instruction, make Witchers exceptionally effective against monsters.
Geralt possesses all standard Witcher mutations along with unusually high mutagen tolerance, contributing to his white hair and exceptional physical capabilities. His abilities include:
- Mastery of steel and silver swords.
- Advanced tracking and refined senses.
- Extensive monster knowledge.
- Resistance to disease, fatigue, and poison.
- Exceptional reflexes and agility.
Geralt is considered one of the most skilled swordsmen on the Continent, known for combining precision, tactical awareness, and practical combat experience against both human and non-human foes.
