This game can be played by watching someone or playing yourself.
Split the players into two teams, the first team is drinking with the opponent and the other team is drinking with the player. Every time a player loses a Health Point that team must take a drink. If a player loses more than ten Health Points in one go you must finish your drink.
If a player loses a legendary monster, someone from the other team gets to nominate someone to take a shot. The winning team at the end of the game also gets to nominate someone to take a shot. So pick your player wisely!
