Trivia

 * The drunken master archetype was popularized by Jackie Chan in the movie Drunken Master. The name of this skill is possibly a tribute to that film and its sequels.
 * The figure in the icon looks suspiciously like the stocky, cane-using character Bo' Rai Cho, from the Mortal Kombat series of games, who also embodies the drunken master archetype.
 * The skill, the film, and the character are all inspired by the Zui Quan martial arts style.
 * The skill follows the same mechanics as the skill from "Fallout Tactics" with a "perk" called "Drunken Master" (named after the Jackie Chan movie). Increased combat whilst innebriated." http://fallout.wikia.com/wiki/Drunken_Master
