One of the more interesting features that Age of Wushu players can experience is the ability to tolerate (or not) alcohol. Being 'drunk' in the game adds an evade buff. The higher the tolerance for alcohol, the harder it is to get 'drunk' and earn the bonus.
Drinking and becoming drunk rewards players with a Evade buff during combat. The higher the tolerance of a player, the more alcohol is required to remain drunk. If a player drinks too much, they will no longer be able to evade and lose mobility in combat or in regular travels. Certain NPCs can unlock random encounters if they enjoy seeing a drunk master stumbling across the streets on a regular basis. Be wary of your Schools Rules to make sure that you are permitted to drink without being disciplined by your sect.
