The Axii sign is a magical ability that allows witchers to temporarily stun, when used quickly, or control, when used in duration, their enemies. Stunning an enemy allows a witcher to bring their guard down while using it as mind control has the foe let their guard down or attack their allies.

Axii is also a social sign for witcher, allowing them to influence people in conversations, but it's not always the best choice. Other people will notice when you use Axii on someone and those whom are strong willed are able to resist it, sometimes getting a witcher into more trouble than they needed. Use it well.
