The Witcher race features some fairly powerful bonuses compared to the vanilla game's races, regenerating stats like health and magicka 2-3 times as fast as other races. The race also boasts enhanced damage for unarmed combat, with the Witcher race's punches being three times as strong as that of other races.
The mod also adds the Witcher franchise's Aard and Igni signs, with the modder intending to add more in the future.
The mod's creater, RobA, suggests pairing the Witcher race mod with a previously released Skyrim mod titled 'A Witcher's Adventure'.
